PRA paper for Tony and a few friends!

Tony, who is spending the second batch of his fellowship here in Belfast, just published a paper in Phys. Rev. A with colleagues at University of Calabria, Universidade Federal do Rio Grande do Norte/Universitat Autonoma de Barcelona, and Universitaet des Saarlandes/University College Cork. The work discusses the possibility of routing of quantum information using quantum spin chains and examines the fidelity of the process against the parameters of the models being considered.

All the details of the work can be found in

Congrats, Tony!!

All-QTeQ paper in PRL highlighted by the Editors!!

Great news for the QTeQ group!! The work by Laura, Gabriele and Mauro on the interferometric reconstruction of the statistical properties of the work done on a quantum system subjected to a process has been published in Phys. Rev. Lett. and is among the “Editors’ suggestions” of this week.

The paper reports on a new way to infer the characteristic function of work distribution which holds the promise to be soon implemented experimentally. Check out the details of the proposed scheme in

Remarkably, this is the first all-QTeQ letter since 2011, and is thus special for the group!

A closely related paper (among the Editors’ highlights as well) has been published simultaneously by our colleagues (and friends) working at the Oxford and Pisa groups

Quantum themodynamics is getting hot indeed…
