Seminar

Sophie Schirmer, University of Cambridge

Abstract

I will cover the basics in terms of the control objectives and algorithms, details about the implementation, and recent results about the convergence behaviour, control landscape, and field characteristics and similarities and differences we see in Markovian vs Non-Markovian systems.

Abstract

I will derive provably-tight two-sided estimates of the reversibility of an
arbitrary quantum channel in terms of entanglement fidelity and on the
conditional min-entropy of an arbitrary bipartite mixed quantum state. Channel reversals have been studied by a number of research groups under the banner of "Approximate quantum error recovery."
