Hi all,
please join us on Monday at 4pm for a quantum information seminar by
Saman Beigi.
Title: *Information Theoretic Benefit of Entanglement in Classical
Communication Settings *
Speaker: *Salman Beigi* (Institute for Research in Fundamental Sciences,
Tehran)
Abstract:
Expressions of several information theoretic quantities involve an
optimization over auxiliary quantum registers. Entanglement-assisted
version of some classical communication problems provides examples of
such expressions. Evaluating these expressions requires bounds on the
dimension of these auxiliary registers. In the classical case such a
bound can usually be obtained based on the Caratheodory theorem, but we
know almost no method to bound the dimension of auxiliary quantum
registers. In this talk to compare the classical and quantum sides of
the problem the notion of "quantum convexification" will be defined. It
will be shown that quantum convexification is strictly richer that the
usual classical convexification. Moreover some techniques will be
discussed which might be useful for bounding the dimension of quantum
auxiliary registers.
Date: Monday, May 27, 2013 - 4:00 pm

Best,
Markus
