Dear Friends,
On Thursday, December 6, there will be an ITAMP topical lunch discussion.
Tea Room (P-226) @ CfA (60 Garden Street)
Time: 12:00-1:30
As always pizza will be served.
Speaker: Chris Chan
Title: Some new perspectives and applications of open quantum systems
Abstract:
Quantum information processing relies on an accurate account and
controllability of the quantum correlation among the system, the
control and the environment. Not only does the study of open quantum
systems provide a theoretical understanding of the fundamental
decoherence mechanism, but also enable scientists to engineer useful
quantum operations to manipulate various quantum systems. Here, we
will present two new perspectives along this direction: we will
introduce a theoretical approach to treat open quantum system problems
using diagrammatic techniques in the same spirit of the Keldysh
non-equilibrium Green's function in order to go beyond the existing
Master equation paradigm; and we will describe a new proposal to
generate distant qubits entanglement by projective measurements of the
multiphotonic environment.
Looking forward to seeing you there,
Misha Lemeshko
