Nineteenth Arnold Sommerfeld Lecture Series, 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.
