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.

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.

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.

Chinese Scientists Make Breakthrough in Quantum Computing
Chinese scientists have recently made a breakthrough in quantum computing. Pan Jianwei and his colleagues from the University of Science and Technology of China achieved the generation, manipulation and detection of atomic spin entanglement by using ultra-cold atoms in optical lattices, which is a great step towards the scalable quantum information computation and quantum simulation based on ultra-cold atoms. According to previous research, ultra-cold atoms in optical lattices offer a great promise to generate entangled states for scalable quantum information processing owing to the inherited long coherence time and controllability over a large number of particles. The process of generating entangled states has three stages. Pan and his colleagues have finished the first stage, which is to produce regularly arranged entangled atom-bits pairs. "We have compared our work with others in the world. We found that other scientists are capable of produce many atoms, but they cannot produce entangled pairs or using quantum manipulation to control them, or measure the quantum state. We are the first team in the world that have managed to produce entangled atom pairs, manipulate them and measure the quantum state. So we are leading the world in this area," said professor Yuan Zhensheng from the University of Science and Technology of China. The new breakthrough is also seen as a great step towards faster quantum computing. "Quantum computer is much faster than the digital computer we are using right now. The goal of our research is to make the quantum computing upgradable and to put it in a bigger mechanism so that it will be usable. The result of our research can be used in faster quantum computing," said Yuan. "Nature Physics," an authoritative academic journal, said that their work "paves the way to create larger highly entangled states, such as 1D and 2D cluster states, the main resource for measurement based quantum computing". Quantum computing studies theoretical computation systems (quantum computer) that make direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data.

Advances in quantum cryptography for free-space communications
Quantum mechanics provides methods of encryption that are secure from eavesdropping attacks against the quantum channel. The National Institute of Standards and Technology (NIST; Gaithersburg, MD) has developed a high-speed quantum key distribution test bed incorporating both free-space and fiber systems. In this video, Joshua Bienfang of NIST talks about the quantum cryptographic system that operates over a 1.5-kilometer free-space link on the NIST campus. These quantum communication systems rely on cryptographic key known to both the sender (Alice) and receiver (Bob). Transmitting at 1.25 gigahertz, any intrusion into the system would be detected by comparing data at the transmitting and receiving end. Bienfang is a physicist in the Electron and Optical Physics Division at NIST, where he works on quantum cryptography.

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

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.

How can quantum physics be applied in communications?
How exactly can quantum physics be applied in communications? Starting with information processing, in normal silicon computer chips, real-world information is converted into digital data, which is rendered in either one of two states: 0 or 1. In quantum computers, digital data can exist in both states simultaneously, regardless of distance. That greatly increases the amount of digital data that can held. China's quantum satellite will beam individual entangled quantum particles between space and ground stations. According to the project team, such communication methodology could be applied in about 10 years in fields including online banking and military affairs.

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.

Episode 2: Carlo Rovelli on Quantum Mechanics, Spacetime, and Reality
https://www.preposterousuniverse.com/podcast/2018/07/10/episode-2-carlo-rovelli-on-quantum-mechanics-spacetime-and-reality/ Quantum mechanics and general relativity are the two great triumphs of twentieth-century theoretical physics. Unfortunately, they don't play well together -- despite years of effort, we currently lack a completely successful quantum theory of gravity, although there are some promising ideas out there. Carlo Rovelli is a pioneer of one of those ideas, loop quantum gravity, as well as the bestselling author of such books as Seven Brief Lessons on Physics and the recent The Order of Time. We talk about how to make progress on this knotty problem, including whether string theory will play a role (Carlo thinks not). Carlo Rovelli is a professor of theoretical physics at the Centre de Physique Théorique de Luminy of Aix-Marseille University in France. In 1988, he and Abhay Ashtekar and Lee Smolin introduced the idea of loop quantum gravity. He is also the author of the "relational" interpretation of quantum mechanics.

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.

Machine Intelligence and Quantum Information Processing - Peter Wittek
Machine Intelligence and Quantum Information Processing Peter Wittek (ICFO, peterwittek.com) IFF-CSIC seminar, Jan. 13th 2017 Slides: https://goo.gl/0xK1MD Abstract: Statistical learning theory is rich in results that changed the way we process and think about data. Furthermore, the theory offered a fresh perspective on artificial intelligence. Applications are countless and much progress has been made in applying learning schemes in quantum control problems. Quantum information processing and quantum computing are the next frontier for machine learning, but benefits work both ways: quantum-enhanced learning is also a promising research direction, but we must generalize known classical results to the quantum case to fully understand the limits and possibilities. This talk gives an introduction to the core concepts in learning theory, and then looks at the major challenges in the intersection of machine learning, artificial intelligence, and quantum information processing.

John Preskill: Quantum information and spacetime (I)
I will review how tools from quantum information theory are providing a fresh perspective on some of the deepest problems in particle physics and gravitation. The first lecture will be a brisk overview of the current status of fundamental physics, followed by a discussion of entanglement in quantum field theory and of the properties of quantum black holes. The second lecture will be an introduction to AdS/CFT duality in quantum gravity, emphasizing the emergence of spacetime from entanglement and the role of quantum error correction. I know it sounds scary, but I’m a physicist, so it will be perfectly safe.

2013 Asia Research Intitute - Everyday World Obey Quantum Mechanics?
SPEAKER : Nobel Laureate Sir Anthony Leggett SYNOPSIS : It is perhaps Hegel more than any other thinker who gave to the arts a paramount importance in justifying the dominance of one nation over all other nations in a given epoch of world history. As a modality of absolute spirit, the arts are the media through which a nation recognizes the unique spiritual principle that distinguishes it from other nations. The arts of a nation allow posterity to discern its contributions to world historical progress, especially whether it embodies the world spirit in a given epoch. Hence, the arts function to justify the violent hierarchy between nations that structures the world. Accordingly, world history's court of judgment is also a forum for the comparative recognition of aesthetic forms. This elaborate philosophical account of national cultural capital has informed official projects of national cultural development ranging from the Goethe Institute to attempts by postcolonial nations to cultivate a national literature or aesthetics. The tacit assumption of these projects is that national arts have a causal relation to a nation's progress because they symbolically express the level of progress attained and also help to stimulate further progress. This paper examines how this model of cultural capital has been radically transformed in contemporary globalization where the cultural capital of a nation is no longer primarily located in its artistic production but rather in its ability to accumulate works of art with a global significance and the promotion of the arts on a global stage. It suggests that these strategies of purchasing (as opposed to producing) artistic capital are fundamentally connected to the accumulation and cultivation of human capital through transnational migration.

Corey is Broken Forever
An international team led by the Austrian physicist Anton Zeilinger has successfully transmitted quantum states between the two Canary Islands of La Palma and Tenerife, over a distance of 143 km. The previous record, set by researchers in China just a few months ago, was 97 km. Breaking the distance record wasn't the scientists' primary goal though. This experiment provides the basis for a worldwide information network, in which quantum mechanical effects enable the exchange of messages with greater security, and allow certain calculations to be performed more efficiently than with conventional technologies. In such a future 'quantum internet', quantum teleportation will be a key protocol for the transmission of information between quantum computers.
