Prof. Shoucheng Zhang discusses three pillars of information technology: quantum computing, AI and blockchain. He presents the fundamentals of crypto-economic science, and answers questions such as: What is the intrinsic value of a medium of exchange? What is the value of consensus and how does it emerge? How can math be used to create distributed self-organizing consensus networks to create a data-marketplace for AI and machine learning?
Prof. Zhang is the JG Jackson and CJ Wood professor of physics at Stanford University. He is a member of the US National Academy of Science, the American Academy of Arts and Sciences and a foreign member of the Chinese Academy of Sciences. He discovered a new state of matter called topological insulator in which electrons can conduct along the edge without dissipation, enabling a new generation of electronic devices with much lower power consumption. For this ground breaking work he received numerous international awards, including the Buckley Prize, the Dirac Medal and Prize, the Europhysics Prize, the Physics Frontiers Prize and the Benjamin Franklin Medal.
He is also the founding chairman of DHVC venture capital fund, which invests in AI, blockchain, mobile internet, big data, AR/VR, genomics and precision medicine, sharing economy and robotics.
Shoucheng Zhang: "Quantum Computing, AI and Blockchain: The Future of IT" - Talks at Google
Thank you so much. It's a great pleasure for me to come here to Google but also a special privilege to be introduced by Diana over a. But also we have been constantly exchanging ideas. And today I like to talk you talk to you. What about eye view as the free frontiers of information technology for the future. Hunton computing artificial intelligence and block change but especially also the possible symbionts is among these three major trends thinking the same thing the world. There are many experts in each one of those subjects but I think the really exciting opportunity is possibly the conference or the symbiosis among these three major trends of the future of information technology. Let me start with a story of recent scientific discovery. A recent discovery that you had a long history. So a lot of great discoveries in science also relates to some deep changes in philosophy we seem to live in a world of opposites a world of dualism we have whenever we have positive numbers we have negative numbers. When we have credits we have debts we have ying and yang. Good and Evil Angels and Demons. But in the natural world there is also a counterpart to deice philosophy of the opposites or the duality. So in 1928 the great perhaps the one of the greatest theoretical physicist of all time Poda Iraq was trying to unify Einstein's theory of special relativity with quantum mechanics and the process of doing so. He was doing some mathematical derivations.
He had to income to operation of square root and then he remembered from his high school days that the square root of nine is not just three because three times he is nine but also minus three because minus three times the ministry is also a man. So whenever you take a route you have to take both the positive and negative roots. At that time was very perplexing. What that negative rude me. And he actually had one brief stroke of genius. He predicted that for every matter in the world. That's the opposite matter. And when you visit Westminster Abbey you can try to find pack commemorating the famous Dirac equation and teaching attendee 12. One of the most humbling experience in my life is to receive a Polaroid Iraq medal. So just I said whenever you take the square root to have a positive branch and a negative branch and he brilliantly interpreted the Medvid negative branch to be a universal law of nature that for every particle there in the universe there is also a Tea Party. Except at the time everybody viewed this beautiful equation but except at the time of twenty eight when he made peace prediction there was simply no anti matter. So for example the matter of the electron will be something that has a positive charge but it's a mess. The Proton has the opposite charge to the electron behests 2000 times more the mass as the election so nobody believed teams. Then you know what he said. He said My equation is so beautiful. You guys simply just go look for it and people are. And he was lucky and five years later in cosmic ray radiation it's very hard to naturally produce that on Earth.
But in the cosmic ray radiation people discovered anti matter namely the positron which has exactly the same mass but the opposite charge of the electron. So I think this is the one of the greatest prediction of all humanity. It's something conceived of beauty also turned out to be true today where actually use these anti matter medical devices. A famous medical imaging technique caught PET scan positron emission tomography that was actually based on these anti particle the positron. It also captured the imagination of Hollywood. So this famous novel and a movie of The Da Vinci Code. Many of you have read the book and saw the movie but there's also a sequel to it's called NGOs and demons also played by. Also the book by Dan promp also played by Tom Hanks. Basically the novel depicts the epic epic struggle between angels and demons copulating. In the end the relation of particles and antiparticles. So actually it's the highest information density one can possibly achieve anywhere in the universe. If you have anti matter with matter the energy they release is the most powerful they can ever be. But it's also a fun analogy. Just us have and your way have Bement whenever we have positive particle we have the opposite antiparticle but human creatures city didn't stop there. So after Iraq's prediction is viewed as one of the greatest of predictions of war time Curiosity didn't stop there. So there was a another great theoretical physicist but somewhat elusive. During his time in the name Ettore Iran. And he asked a curious question.
Could that be matter which Dunham had and he made a particle which is its own antiparticle particle which would not have its own would not have antiparticle its own particle. Is that possible. So he asked this question. And he also wrote down a beautiful equation which described it. But this time he was not so lucky. Nobody believed him and nobody found it so he actually got very disappointed about that. So ever since then it became a mystery. Find him into Assize so we have a fundamental and most wanted list.
