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.
