Superluminal signalling and chaos in nonlinear quantum dynamics
Marta Emilia Bielińska, Michał Eckstein, Paweł Horodecki
Nonlinear quantum dynamics is often invoked in models trying to bridge the gap between the quantum micro-world and the classical macro-world. Such endeavors, however, encounter cha…

Prospects for quantum process tomography at high energies
Clelia Altomonte, Alan J. Barr, Michał Eckstein +2
In quantum information theory, the evolution of an open quantum system -- a unitary evolution followed by a measurement -- is described by a quantum channel or, more generally, a q…
