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

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.
