Physics@FOM Veldhoven 2016, Anton Zeilinger - Quantum teleportation and entanglement
Quantum teleportation, entanglement, and Einstein’s question, “What is light?” It is well known that Einstein received the Nobel Prize for the groundbreaking idea of 1905, his annus mirabilis, that light consists of particles, today called photons. In 1935, he discovered together with Podolsky and Rosen that two quantum systems can be connected stronger than in classical physics. For that situation the Austrian Nobel Prize winner Erwin Schrödinger coined the name “entanglement” and called it “the essential feature of quantum mechanics” while Einstein, dismissed it as “spooky action at a distance”. Technical progress in creating and handling entangled photon states not only led to experimental realization of such entangled states but also the discovery of novel phenomena, including, for example, multi-particle entanglement and quantum teleportation. These are not just intellectual curiosities, but they lay the foundations for a new information technology, with concepts such as quantum communication, quantum cryptography and quantum computation. In the talk, Zeilinger presents some of the most recent experimental results, particularly on long-distance quantum communication and on the implementation of quantum states in higher-dimensional Hilbert spaces. He also discusses future possible applications in quantum information systems. These will, for example, include experiments using satellite-based quantum communication on a worldwide scale. Towards the end of his life Einstein commented that despite years of conscious brooding, he did not come closer to answering the question “What is light?” It would be fascinating to know his position about these recent developments.

Quantum Teleportation Is Real, Here's How It Works
Scientists successfully achieved earth-to-space quantum teleportation, but what exactly does that mean? How Quantum Computing Will Change The World! - https://youtu.be/3BKIJCTLy-s Read More: Teleportation: Photon particles today, humans tomorrow? http://www.bbc.co.uk/news/science-environment-40594387 “Chinese scientists say they have "teleported" a photon particle from the ground to a satellite orbiting 1,400km (870 miles) away. For many, however, teleportation evokes something much more exotic. Is a world previously confined to science fiction now becoming reality? Well, sort of. But we are not likely to be beaming ourselves to the office or a beach in the Bahamas anytime soon. Sorry.” China Demonstrates First Intercontinental Quantum Communication https://www.seeker.com/tech/china-demonstrates-first-intercontinental-quantum-communication “The first public demonstration of long distance quantum communication came a few weeks after China unveiled a new 1,240-mile-long optic-fiber quantum communication network between Beijing and Shanghai for the “military, finance, and government affairs fields.” In May, Chinese researchers announced a new quantum computer that they claimed was 24,000 times faster than competing designs, too.” Quantum Data Storage in a Single Atom Brings New Computing Era Closer to Reality https://www.seeker.com/tech/quantum-data-storage-in-a-single-atom-brings-new-computing-era-closer-to-reality “We’re on the verge of a quantum computing revolution.

Amazing World of Quantum Entanglement - Full Documentary
Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon—two subatomic particles that mirror changes in each other instantaneously over any distance—is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions. Scientists are working to decipher and harness the power of quantum mechanics, but the strange nature of entanglement and other quantum phenomena continues to confound researchers, posing new and mystifying questions. From an experiment studying quasars at opposite ends of the universe to probing the interactions of elementary particles, researchers are gathering insights that could shatter the laws of space and time and provide a radical new understanding of the universe. This documentary presents cutting-edge work and considers various implications of the coming quantum revolution that begins with making sense of the seemingly absurd. By entangling particles on a satellite and shooting them down to Earth, China may have just set the tone for a global “quantum space race.” In a new study in the journal Science, Jian-Wei Pan, a physicist at the University of Science and Technology of China in Shanghai, and his colleagues report that they were able to entangle photons aboard a satellite 300 miles above Earth and then beam those particles to three ground stations across China—each separated by more than 700 miles. It’s an unprecedented feat. Not only were the particles entangled in space (scientists have never done this before), but they retained their bizarre connection even after they’d been separated by a distance 10 times the previous record for what’s called “quantum teleportation.” Entanglement still boggles physicists’ minds to this day, even though our understanding of it has its origins in the renaissance of early 20th-century quantum theory research. According to quantum mechanics, particles can be in different “states” at once, and when they’re observed, those superimposed states collapse into just one. When particles are “entangled,” their states are linked together across space—when the one particle is measured, the other particle’s properties become frozen as well. Einstein wasn’t a fan of this idea because it suggested that communication between particles could travel instantaneously—i.e., faster than the speed of light. Though it sounds like a pointless exercise to make “twin” particles and send them careening away from each other, scientists are doing just that in order to pioneer what’s called “quantum communication,” an ultra-private way of sending messages. Because observation of one entangled particle immediately affects its partner, information sent via quantum methods can’t be hacked without it being very obvious to the other party involved.

Prof. Dr. Anton Zeilinger speaks on quantum physics at UCT
Prof. Dr. Anton Zeilinger speaks on quantum physics at UCT. Professor Zeilinger is one of the world’s leading quantum physicists. He works both on theoretical and experimental foundations of quantum physics, and a primary focus of his research is entanglement, the deep connectedness of distant systems. He started the field of multi-particle entanglement, which became a crucial ingredient for any future quantum computer. He carried out the first entanglement-based quantum communication, the first quantum teleportation, the first experimental quantum teleportation and the first quantum cryptography with entangled photons. These groundbreaking achievements contributed significantly to a new understanding of fundamental issues in the interpretation of quantum mechanics, where information is the central theme. Another focus of his work has been to investigate quantum features of large particles and the transition between quantum mechanics and classical physics. Zellinger made the first experimental demonstration of quantum interference of Buckminster-Fullerenes and biologically relevant macromolecules. He is currently studying the quantum behavior of real mechanical systems, such as mechanical oscillators (micro-mirrors).

Anton Zeilinger – Breaking the Wall of Illusion @Falling Walls 2014
BREAKING THE WALL OF ILLUSION How Quantum Physics Questions Our Perception of Reality Anton Zeilinger Professor of Physics at the University of Vienna and President of the Austrian Academy of Sciences Plato’s famous Parable of the Cave illustrates the idea that human beings will never be able to see the truth until they leave the cave in which they are held prisoners, where they are forced to watch shadows on the dark walls and see only projections instead of reality itself. It has been suggested that this old metaphor of our limitations of understanding might well describe the relationship between classical physics, which studies phenomena of the sensible reality, and quantum physics, which explores what lies underneath. Quantum physics challenges traditional perceptions of reality: it teaches us that matter is mainly void, that objects can simultaneously exist in different places, and that they are physically correlated in space and time through a phenomenon called “entanglement” – what Einstein called “spooky action at a distance”. A pioneer in quantum information and the foundations of quantum mechanics, the Austrian physicist Anton Zeilinger has been awarded the first Newton Medal and the 2010 Wolf Prize in Physics, among other recognitions. He realised many important quantum information protocols for the first time and helped build the basis for future quantum communication networks, the long-distance transmission of signals using the properties of entanglement, powerful quantum computers, and quantum cryptography, which might bring us perfect data security. At Falling Walls, Zeilinger demonstrates how the growing knowledge of quantum physics will change the way we perceive ourselves and the reality surrounding us.

STUDY WITH ME | Quantum Measurement & Observables
Follow along with this Quantum Objects course at https://brilliant.org/tibees/ The important ideas that I discuss: 1. At the limit of many quantum measurements, the average will always approach the classical result, even if individual experiments appear to violate the classical law. This is called the classical limit. 2. Quantum measurements are not as gentle as classical measurements. Sometimes measuring a quantum state can change the state for all future measurements. 3. Observers can change the state of quantum objects. Quantum states are reset by observation itself, though the point in the experiment when this occurs is still the subject of active debate.

Because it depends on classical communication, which can proceed no faster than the speed of light, it cannot be used for faster-than-light transport or communication of classical bits. While it has proven possible to teleport one or more qubits of information between two (entangled) atoms,this has not yet been achieved between anything larger than molecules.

REALITY LOST Excerpt 6. Quantum key distribution explained.
SYNOPSIS At the beginning of the 20th Century, a major shift took place in science. Scientists started doing experiments with unprecedented precision -- fiddling with single particles, atoms, and electrons. And they got bewildered. Small objects seemed to have sort of fuzzy properties. What's more, the very act of observing them, of measuring them, seemed to bring them to life, excavate them from a vague domain. The equations of quantum mechanics were beautiful. They generated astonishingly correct answers for mind-boggling questions about the exotic micro world. But there was a price to pay. Objective reality had to go.

Internet Cryptography for the Quantum World
Quantum mechanics has profound implications for cryptography. It tells us that perfectly-secure key-exchange is possible, and that factoring is not a good basis for secure encryption. More generally, it tells us that quantum data and quantum computation are more fundamental than their classical counterparts. As a result, it stands to reason that the Internet of the future will be "fully-quantum," with all participants able to prepare, send, and compute on quantum states. In this talk, I will discuss how such an Internet might be secured. A starting point is to show how to securely transmit many large quantum states using a single short key, and how to authenticate such transmissions. Then, one can attempt to translate many of the great achievements of classical modern cryptography to the quantum setting. In some cases (such as CPA-secure encryption), this is relatively straightforward. In general however, the unique features of quantum-mechanics (such as no-cloning and the destructiveness of measurements) present significant obstacles. I will show how to overcome these obstacles in some cases, and how to design schemes for encrypting quantum states (and detecting forged states) under the strongest possible security guarantees (i.e., CCA.) I will also discuss current work on powerful primitives (such as black-box obfuscation) that are impossible classically but may exist quantumly.

Quantum mechanics (QM -- also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at nanoscopic scales where the action is on the order of the Planck constant. It departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. Quantum mechanics provides a substantially useful framework for many features of the modern periodic table of elements including the behavior of atoms during chemical bonding and has played a significant role in the development of many modern technologies. In advanced topics of quantum mechanics, some of these behaviors are macroscopic (see macroscopic quantum phenomena) and emerge at only extreme (i.e., very low or very high) energies or temperatures (such as in the use of superconducting magnets). For example, the angular momentum of an electron bound to an atom or molecule is quantized. In contrast, the angular momentum of an unbound electron is not quantized. In the context of quantum mechanics, the wave--particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons, and other atomic-scale objects. The mathematical formulations of quantum mechanics are abstract. A mathematical function, the wavefunction, provides information about the probability amplitude of position, momentum, and other physical properties of a particle. Mathematical manipulations of the wavefunction usually involve bra--ket notation which requires an understanding of complex numbers and linear functionals. The wavefunction formulation treats the particle as a quantum harmonic oscillator, and the mathematics is akin to that describing acoustic resonance. Many of the results of quantum mechanics are not easily visualized in terms of classical mechanics. For instance, in a quantum mechanical model the lowest energy state of a system, the ground state, is non-zero as opposed to a more "traditional" ground state with zero kinetic energy (all particles at rest). Instead of a traditional static, unchanging zero energy state, quantum mechanics allows for far more dynamic, chaotic possibilities, according to John Wheeler. The earliest versions of quantum mechanics were formulated in the first decade of the 20th century. About this time, the atomic theory and the corpuscular theory of light (as updated by Einstein)[1] first came to be widely accepted as scientific fact; these latter theories can be viewed as quantum theories of matter and electromagnetic radiation, respectively. Early quantum theory was significantly reformulated in the mid-1920s by Werner Heisenberg, Max Born and Pascual Jordan, (matrix mechanics); Louis de Broglie and Erwin Schrödinger (wave mechanics); and Wolfgang Pauli and Satyendra Nath Bose (statistics of subatomic particles). Moreover, the Copenhagen interpretation of Niels Bohr became widely accepted. By 1930, quantum mechanics had been further unified and formalized by the work of David Hilbert, Paul Dirac and John von Neumann[2] with a greater emphasis placed on measurement in quantum mechanics, the statistical nature of our knowledge of reality, and philosophical speculation about the role of the observer. Quantum mechanics has since permeated throughout many aspects of 20th-century physics and other disciplines including quantum chemistry, quantum electronics, quantum optics, and quantum information science. Much 19th-century physics has been re-evaluated as the "classical limit" of quantum mechanics and its more advanced developments in terms of quantum field theory, string theory, and speculative quantum gravity theories. https://www.youtube.com/watch?v=ZsVGut7G-dU quantum solace, quantum world, #quantum

The Dalai Lama and Quantum Physics (2007) 6/6
"Maybe knowledge is as fundamental, or even more fundamental than reality." (A.Z.) The austrian quantum physicist Anton Zeilinger explains to the Dalai Lama some basics of quantum physics and some results of the last 9 years of experiments in quantum mechanics. Themes: Atomism, randomness, the phenomenon, interdependence, the role of the observer in quantum physics and buddhism (Parts 1-3). Explanation of the quantum computer (Parts 4-6). Dialogue Leaders: Anton Zeilinger and Arthur Zajonc. Questions from Matthieu Ricard and Wolf Singer. Excerpt of: "Mind and Life XIV" - Dialogues on "The Universe in a Single Atom". Day 1 Afternoon Session (April 9th, 2007) (Held at His Holiness the Dalai Lama's residence in Dharamsala, India) In this video the sequences with longer translations to the Dalai Lama and the conversations in Tibetan (together about 20 minutes) are not included. The version without cuts is available here (Day 1 pm): http://www.youtube.com/watch?v=fO-K13cfJwo Day 1 am (with introduction from the Dalai Lama): http://www.youtube.com/watch?v=Dmlnk-iLiYc Anton Zeilinger (born on 20 May 1945 in Ried im Innkreis, Austria) is an Austrian quantum physicist. He is currently professor of physics at the University of Vienna, previously University of Innsbruck. He is also the director of the Vienna branch of the Institute for Quantum Optics and Quantum Information IQOQI at the Austrian Academy of Sciences. Zeilinger has been called a pioneer in the new field of quantum information and is renowned for his realization of quantum teleportation with photons (Source: Wikipedia). In addition to being a scientific autobiography, the Dalai Lama's book "The Universe in a Single Atom: the Convergence of Science and Spirituality" highlights those issues he feels are most important in the "convergence of science and spirituality."

How Does a Quantum Computer Work?
For more on spin, check out: http://youtu.be/v1_-LsQLwkA This video was supported by TechNYou: http://bit.ly/19bBX5G A quantum computer works in a totally different way from a classical computer. Quantum bits or 'qubits' can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N classical bits. Thank you to Andrea Morello and UNSW. For more info, check out: http://bit.ly/17wZ7lt

What Is Entanglement Anyway? Chris Fields
Entanglement or non-separability is the core idea of quantum theory. It is a simple idea: the universe is not a bunch of independent parts, but is rather one entity that evolves through time as one entity. That's it. The problem is that this means there's no such thing as causation. This is very hard to wrap your head around. Quantum theory is extraordinarily accurate, and our knowing quantum theory is why we have things like cell phones and computers. But what is quantum theory, really? Why is entanglement its primary prediction? This talk will explain what quantum theory is. I will show that quantum theory has nothing to do with tiny particles, wave-function collapse, or Schroedinger's cat. Quantum theory is about how observers obtain information about the world. It is, in particular, about how observers who have memories and use language obtain information about the world. It is, in other words, about how you and I interact with perfectly ordinary things like tables and chairs and each other. You will leave this talk with a new understanding of quantum theory, and a new appreciation for entanglement. Chris Fields is an interdisciplinary information scientist interested in both the physics and the cognitive neuroscience underlying the human perception of objects as spatially and temporally bounded entities. His current research focuses on deriving quantum theory from classical information theory; he also works on cell-cell communication and cellular information processing, the role of the “unconscious mind” in creative problem solving, and early childhood development, particularly the etiology of autism-spectrum conditions. He and his wife, author and yoga teacher Alison Tinsley, recently published Meditation: If You’re Doing It, You’re Doing It Right, in which they explore the experience of meditation with meditators from many walks of life. Dr. Fields has also been a volunteer firefighter, a visual artist, and a travel writer. He currently divides his time between Sonoma, CA and Caunes Minervois, a village in southwestern France.

The Complexity of Quantum Entanglement
Quantum mechanics predicts the existence of correlations among two or more quantum systems that cannot be described merely by shared randomness. Such correlations, termed entanglement, have been analyzed from a foundation perspective since the beginning of quantum theory and, more recently, as a resource for quantum information-theoretic tasks. A fundamental problem in entanglement theory is the following: given the description of a quantum system of two or more parties as a density matrix (a positive semidefinite matrix of unit trace), how can we decide if the state is entangled? In this talk I will show that one can use the Lasserre hierarchy of semidefinite programs to solve the above in quasi-polynomial time, giving the fastest known algorithm for it. The proof of convergence is based on ideas of quantum information theory and gives a new way of understanding the Lasserre hierarchy in general. In particular I’ll also discuss applications of the framework to computing hypercontractive norms and estimating the expansion of small sets in graphs (a problem tightly related to the unique games conjecture).

Colloquium: Saikat Guha - Photonic quantum computing and applications
Title: Photonic quantum computing and applications Abstract(s): In the cluster model of quantum computing, any quantum algorithm can be implemented by an adaptive sequence of measurements at the nodes of a graph, where the nodes are qubits (photons in our case) and edges between two nodes represent entanglement. An entangled cluster in a 2D square lattice topology is known to a resource for universal quantum computing. Photons are a promising candidate for encoding qubits scalably but assembling a large photonic entangled cluster state (using photons and linear optical circuits) is a challenge, since each step relies on probabilistic operations, and losses in transmission and detection. I will describe a new proposal for cluster-model photonic quantum computing that combines ideas from recent work on "boosted" linear optics based Bell basis measurements, percolation theory and quantum error correction for photon loss. In this architecture, small photonic clusters are fused in an efficient “ballistic" fashion, i.e., without any detection-induced feedback, into a long sheet of entangled photons, which can then be re-cast into a logical square-lattice graph for quantum computing. Aside from the obvious uses in general-purpose quantum computing, I will talk about applications of photonic cluster states to a special purpose quantum processor known as quantum repeater, which will be a key enabler to a future quantum internet. Speaker Bio(s): Saikat Guha is an Associate Professor of Optical Sciences at the University of Arizona. He earned his B.Tech. degree in electrical engineering in 2002 from the Indian Institute of Technology Kanpur (India), followed by S.M. and Ph.D. degrees in 2004 and 2008 respectively, from the department of electrical engineering and computer science at the Massachusetts Institute of Technology. His research interests span quantum limits to optical communication and sensing, optical quantum computing, and network information theory. Guha represented India at the International Physics Olympiad in 1998, where he was awarded the European Physical Society award for the experimental component. He was a co-recipient of a NASA Tech Brief award in 2010 in recognition of his work on novel receivers for quantum imaging. His Defense Advanced Research Projects Agency Information in a Photon team won the Raytheon 2011 Excellence in Engineering and Technology Award, Raytheon's highest technical honor, for outstanding research on fundamental limits of optical communication.

The World of Quantum Mechanics Made Simple ~ An Animated Guide - Part 6 (6/6)
This video series is presented for educational and enlightenment purposes only. The series was created by the Cassiopeia Project. For more information visit: http://www.cassiopeiaproject.com The World of Quantum Mechanics Explained ~ An Animated Guide "Spooky, bizarre and mind-boggling are all understatements when it comes to quantum physics. Things in the subatomic world of quantum mechanics defy all logic of our macroscopic world. Particles can actually tunnel through walls, appear out of thin air and disappear, stay entangled and choose to behave like waves. According to Niels Bohr, the father of the orthodox 'Copenhagen Interpretation' of quantum physics, "Anyone who is not shocked by quantum theory has not understood it". Richard Feynman, one of the founders of quantum field theory remarked, "I think I can safely say that nobody understands quantum theory". Quantum mechanics deals with the study of particles at the atomic and subatomic levels. The term was coined by Max Born in 1924. Though the theory works to provide accurate predictions of phenomena at the subatomic scales, there is no real understanding of why it works, what it really means or what implications it has for our world picture. Ergo, the best we can do is present you with the central mystery at the heart of quantum mechanics and show you the way its theoretical structure works to provide real world predictions. Once you decide to go down the rabbit hole, the wonderland of quantum physics, will keep you enthralled forever."

Quantum Double Slit Experiment in Hindi | physics tv india
#pti42 Welcome to your "physics tv India" Quantum Double Slit Experiment in hindi what is Thomas young double slit experiment? https://youtu.be/7PwCHgK_oJo what is SCHRÖDINGER'S CAT experiment? https://youtu.be/9pKFU1sbQl4 Quantum Double Slit Experiment light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles? The experiment was conducted by Thomas Young and is known as Young's Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits and then interfered with itself created a series of light and dark spots. Since the sunlight consists of all colors of the rainbow, these colors were also visible in the projected spots. Young concluded that light consists of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment. The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach. Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young's lecture and the University of Sydney for lending the double slits. what is a black hole in Hindi https://youtu.be/4xLiO-kKIDk what is a white hole in Hindi https://youtu.be/tnfHt25CjBs other videos time travel in future and their cases Hindi link:-https://youtu.be/zd4sdH6lFqE time travel through black hole hindi link:-https://youtu.be/21eHlIpCMb8 time travel in past and their cases Hindi link:-https://youtu.be/9Fqw_Iurx8E what would happen when we travel inside a black hole https://youtu.be/yIuVm8hHp0o Please Give us Your Support Subscribe and Share this Channel With Your Friends Powered by: UNI ISN **Stay Connected with me** Blog:-http://uniisn.com/hi Facebook-https://www.facebook.com/physicstvindia/ facebookGroup:http://bit.ly/2jMjv1r Twitter-https://twitter.com/physicstvindia Google Plus-http://bit.ly/2gMNuQM instagram:-https://www.instagram.com/physicstvindia/ !!==–..__..-=-._; !!==–[email protected]=-._; !!==–..__..-=-._; !! !! !! !! !! \\\|||\\\|||\\\ \\\|||\\\|||\\\PHYSICS TV INDIA \\\|||\\\|||\\\\\\|||\\\|||\\\ special thanks to pixabay ,incomptech, Background Music Credit ---------------------------------------------------------------------- Music by: Music Source: http://www.incompetech.com Artist http://www.incompetech.com Licensed under Creative Commons: By Attribution 3.0 License http://creativecommons.org/licenses/b... -------------------------------------------------------------------------- Disclaimer- Some contents are used for educational purpose under fair use.

Michel Planat - Quantum Information and Quantum Contextuality in Grothendieck's Coset Space
QGR visitor and friend Michel Planat (Senior Research Scientist, University of Franche-Comte, FEMTO-ST) posits the geometry of cosets in the subgroups of the two-generator free group nicely fits, via Grothendieck's dessins d'enfants, the geometry of commutation for quantum observables. In previous work, it was established that dessins stabilize point-line geometries whose incidence structure reflects the commutation of (generalized) Pauli operators. Now we find that the nonexistence of a dessin for which the commutator precisely corresponds to the commutator of quantum observables on all lines of the geometry is a signature of quantum contextuality. This occurs first at index : in Mermin's square and at index in Mermin's pentagram, as expected. Commuting sets of -qubit observables with are found to be contextual as well as most generalized polygons. A geometrical contextuality measure is introduced.
