The Quantum Physics of Harry Potter

Post for The Quantum Physics of Harry Potter From invisibility cloaks to teleportation, Harry Potter’s world is filled with mystery and wonder. Yet this magical world is not so different from the world we inhabit. Just beneath the surface of our ordinary lives is a strange quantum reality.

Women in Physics Canada

We invite applications to "Women in Physics Canada", a three-day conference which will take place from Tuesday, July 19 to Thursday, July 21, 2011 jointly at Perimeter Institute and the Institute for Quantum Computing, Waterloo, Ontario. This conference, aimed at undergraduates and early graduates, is intended to provide support to young women in physics, and to encourage them to continue in a career in physics.

John Calsamiglia: Local vs Collective measurements in statistical inference

John Calsamiglia, Universitat Autònoma de Barcelona

Abstract

I will present three problems in quantum statistical inference that all stem from the difference between local and collective measurements on multipartite states.

The first one is that of hiding a secret direction in a multipartite state with the promise that the parties cannot learn the direction if they perform local operations and classical communication, but can accurately retrieve it if they perform collective measurements.

Vladimir Korepin: Entanglement in quantum spin chains

Vladimir Korepin, Stony Brook

Abstract

The main subject of the lecture is entanglement spectrum. After a short introduction the author will consider density matrix of a large block of spins on infinite lattice. The spectrum will be compared for the cases of Heisenberg chain and VBS states. Potential applications will be discussed.
