Dear all,
There are two talks that may be of interest this week:
Nicolas Gisin will speak on "Towards Understanding Quantum Correlations: New Bell tests and simulating Entanglement with Nonlocal Boxes" on Monday at 16:45 in HCI J 7.
and
Wednesday, November 5, 2008 Moty Heiblum Weizmann Institute, Rehovot, Israel
Entangled Electrons in the Solid State: Quantum Interference and Dephasing
I will describe two experiments, where pairs of electrons were entangled in a solid state Mach-Zehnder interferometer, leading to entirely different outcomes. In one experiment a 'which path' detector was entangled with an interferometer, leading to total dephasing of the interference. The lost interference was recovered by doing a 'post selection' type measurement; proving that phase information stayed in the system. In another experiment two remote, indistinguishable electrons were entangled without ever interacting with each other. Since they propagated along different paths, interference took place only due to the electrons' exchange statistics.
