Hi Everyone,
Tomorrow (Friday, 22th at 2pm, Div. Room) we will have a special group
meeting given by Prof. Animesh Datta of University of Warwick, UK. The talk
is focused on quantum imaging and sensing, but Prof. Datta is also
interested in boson sampling and excitonics.
Please see below for the title and abstract of his talk.

Title: Sensing and imaging at the quantum limit
Quantum correlated probes have the potential of delivering enhanced
precision in estimating individual parameters. Obtaining quantum
enhancements in scenarios of wider appeal such as imaging require an
understanding of the quantum limits of estimating several parameters across
multiple modes simultaneously. The problem is made theoretically and well
as practically interesting and non-trivial by the possible
non-commutativity of the optimal measurements needed to attain the quantum
limits for estimating individual parameters. We present developments on the
quantum theory of estimating multiple parameters -- arising from both
unitary dynamics as well as decoherence -- simultaneously in a few
scenarios, and its ramifications in the imaging of real-world samples. Time
permitting, I will discuss some of our recent results on the possible role
of weak measurements in quantum enhanced sensing.
