Vlatko Vedral on the universe as quantum information
The Life Scientific
Vlatko Vedral describes himself as a quantum information practitioner, who believes that our universe is made up of quantum bits of information. It is information, he tells Professor Jim Al-Khalili, rather than energy or matter, the traditional building blocks of classical Newtonian physics, that can help us to understand the nature of reality.Vlatko is Professor of Quantum Information Science at the University of Oxford and the Principal Investigator at the Centre for Quantum Technologies at the National University of Singapore and he talks to Jim in front of an audience at the Cheltenham Science Festival.At high school in Belgrade, in what was then Yugoslavia, young Vlatko was bowled over by the idea that you could take the micro-laws of quantum mechanics, and apply them to the complex systems of the macro world. This drive to see the big picture, was fuelled when, as an undergraduate at Imperial College, London, he saw three words – “Information is physical” – the title of a paper by the IBM physicist, Rolf Landauer. It was a light-bulb moment for Vlatko, who realised that the kind of information processing that the universe is capable of, depends on the underlying laws of physics.This revelation led to Vlatko’s incarnation as a self-confessed “physics fundamentalist” who unashamedly crowns physics the Queen and other disciplines, her servants. It is physics alone, he tells Jim, which can answer the fundamental questions of the universe and discover the ultimate reality.His PhD in 1997 at Imperial College, London, applied quantum mechanics, including super-positioning and entanglement (which Einstein famously called “spooky action at a distance”), to Claude Shannon’s Information theory, making Vlatko one of the pioneers in the field of quantum information.As new quantum computers come on stream, he tells Jim, quantum information practitioners, like him, will have the capacity to simulate complex systems in the macroscopic domain.

Anyone Listening? Quantum Cryptography Applications with Vlatko Vedral
Finding Genius Podcast
Upgrading isn't just for phone systems. Quantum information science tackles the upgrade of old existing technologies, which run by classical physics laws, to those that function in the quantum realm. It's as easy as it sounds: Vlatko Vederal tells listeners what this entails and what possibilities researchers like him are working toward. Listen and learn What order researchers must move in to do this transfer, from quantum cryptography research to large-scale quantum computing, Why quantum cryptography offers a much more secure channel of communication, and What timeline will this upgrade follow and how soon might we be carrying around quantum laptops. Vlatko Vedral is a professor at University of Oxford in Quantum Information Science. He explains his field in helpful terms, comparing classical technologies with quantum technologies like quantum computing applications. His useful analogies give listeners a comprehensive picture of what this will look like and he provides a specific timeline. First, he says, quantum cryptography will take more of a center stage because it's the simplest one to begin with. Then there will be a shift towards implementing quantum memory, and finally, in the next ten years or so, we will see upgrades to large scale quantum computers. His explanation about how quantum cryptography helps elucidate the challenges for all quantum applications. Basically, if two people are trying to communicate using quantum bits, anyone eavesdropping is forced to a take measurement and collapse the communication to classical properties. This makes their listening-in detectable because that action will emit a lower fidelity, giving them away. He and Richard then discuss more fascinating potentials and the challenges they present, which tend to center on the error rate and physical necessities. For example, they must cool an atom to an extremely low temperature. As more cubits are added, the system gets hotter and noisier. Their only current solution is to do error correction, but researchers like Vedral are working towards better techniques. So listen in for these exciting possibilities.

This is my interview with Vlatko Vedral, a professor of quantum information science at Oxford University. We discuss the difference between dynamical laws and principles in physics, the role that the principles of constructor theory play in discovering new dynamical laws, the constructor theory of information, his research (in collaboration with Chiara Marletto) into probing hybrid systems in which quantum mechanical objects interact with gravity, and more.

Convergence VC | Episode 4 - Vlatko Vedral | Hosted by Lawrence Lundy
Convergence VC Weekly Podcast
Lawrence Lundy speaks to Vlatko Vedral Professor of Quantum Information Science at Oxford University & The Center of Quantum Tech at National University of Singapore about convergence in his field and if Quantum will render cryptography and crypto assets useless. If anyone should know its Vlatko, published author of Decoding Reality and over 280 research papers on Quantum Mechanics.
Professor Vlatko Vedral joins the conversation for a fascinating discussion on the integration of quantum physics with finance. Professor Vedral begins with an overview on the concept of information and information theory. They quickly progress into a discussion on the application of information theory to the world of financial markets. Peter and Professor Vedral mention several prominent models used within finance and relate them to problems often associated with models in science. They discuss the quantification of information and its potential use in finance. Next, they relate the example of players strategically beating casinos in blackjack to approaches to finance. The conversation moves to the element of time, and the understanding of time within quantum physics. They discuss whether or not markets are efficient and the relevance of free will. A theological discussion ensues as they both theorize about the nature of the universe. They discuss quantum game theory and wrap up the discussion with a word association game.
