Dear Friends,
On Thursday, January 17, 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: Felipe Herrera
Title: Dynamical generation of entanglement in cold molecular gases
using strong laser pulses
Abstract:
Many-particle entanglement can be found in the ground state of natural
solids and strongly interacting atomic and molecular gases, but it is
still experimentally challenging to generate highly entangled states
between weakly interacting particles in a scalable way. In this talk I
will describe a one-step method to generate maximally entangled
bipartite states with polar molecules in the absence of DC electric
fields. For molecules in an optical lattice with site separation of a
few micrometers, maximally entangled states can be created using
strong off-resonant pulses that are routinely used in molecular
alignment experiments. I will present an entanglement measurement
scheme based on Bell-type measurements in addressable optical lattices
and a global entanglement measure based on traditional microwave
spectroscopy. The robustness of the prepared entangled states with
respect dissipation induced by optical lattice phonons will also be
discussed. If time permits, I will finally overview possible
applications of the scheme for quantum information processing and
quantum metrology.
Looking forward to seeing you there,
Misha Lemeshko
