Leigh Page Prize Lectures: John Preskill, California Institute of Technology, “Quantum Computing and the Entanglement Frontier”, Tuesday, May 3, 2016 4:00 PM - 5:00 PM in Sloane Physics Lab, rm. 59 (Tea at 3:30 pm in SPL 3rd Floor Lounge)
The quantum laws governing atoms and other tiny objects seem to defy common sense, and information encoded in quantum systems has weird properties that baffle our feeble human minds. John Preskill will explain why he loves quantum entanglement, the elusive feature making quantum information fundamentally different from information in the macroscopic world. By exploiting quantum entanglement, quantum computers should be able to solve otherwise intractable problems, with far-reaching applications to cryptology, materials, and fundamental physical science. Preskill is less weird than a quantum computer, and easier to understand.

Aside from enabling revolutionary future technologies, quantum information science is providing powerful new tools for attacking deep problems in fundamental physical science. In particular, the recent convergence of quantum information and quantum gravity is sparking exciting progress on some old and very hard questions.
Leigh Page Prize Lectures: John Preskill, California Institute of Technology, “Holographic Quantum Codes”, Thursday, May 5, 2016 4:00 PM - 5:00 PM in Sloane Physics Lab, rm. 59 (Tea at 3:30 pm in SPL 3rd Floor Lounge)
Two of the most amazing ideas in physics are the holographic principle and quantum error correction. The holographic principle asserts that all the information contained in a region of space is encoded on the boundary of the region, albeit in a highly scrambled form. Quantum error correction is the foundation of our hope that large-scale quantum computer can be operated to solve hard problems. I will argue that these two ideas are closely related, and will describe quantum codes which realize the holographic principle. These codes provide simplified models of quantum spacetime, opening new directions in the study of quantum gravity, though many questions remain.
