2017 Oppenheimer Lecture by John Preskill on Quantum Computing

I follow John Preskill’s blog very closely. When I heard that he gave the 2017 Oppenheimer Lecture at the University of California – Berkeley I knew that this lecture would be an important educational resource.

In the lecture he talks about many things and reminds us that the information about ‘how the system was prepared ‘ is stored in the quantum correlations of the entangled pair and this information can be used for practical purposes in the context of quantum computing.

He also predicts that physicists will be able to create spacetimes that did not exist before by creating highly entangled quantum systems in tabletop experiments in the future.

Quantum correlations have no classical analog. Collectivity of the entangled system – quantum correlations – contain information not found in the individual components of the system. This is a deep subject with many philosophical implications. I hope to write more on this in the future.*

John Preskill is the Richard P. Feynman Professor of Theoretical Physics at the California Institute of Technology, and Director of the Institute for Quantum Information and Matter at Caltech. Preskill received his Ph.D. in physics in 1980 from Harvard, and joined the Caltech faculty in 1983.  Preskill began his career in particle physics and cosmology, but in the 1990s he got excited about the possibility of solving otherwise intractable problems by exploiting quantum physics; he is especially intrigued by the ways our deepening understanding of quantum information and quantum computing can be applied to other fundamental issues in physics, such as the quantum structure of space and time.

* It is hard to beat MathPages when it comes to clarity and insight. If you are studying Quantum Mechanics you should read the “Quantum Entanglement and Bell’s Theorem”  page at the MathPages at some point in your career.
