A Wigner quasiprobability distribution of work
In this article, we introduce a quasiprobability distribution of work that is based on the Wigner
function. This proposal rests on the idea that the work conducted on an isolated system can …

Experimentally reducing the quantum measurement back action in work distributions by a collective measurement
In quantum thermodynamics, the standard approach to estimating work fluctuations in
unitary processes is based on two projective measurements, one performed at the …
