Generalized Loschmidt echoes associated with operational quantum non-Markovianity
Cecilia Cormick, Adrián A. Budini
Non-Markovianity can be characterized by performing a series of successive measurements and analyzing departures of the corresponding outcome statistics from a Markovian probabilis…

Detecting quantumness with generalized Loschmidt echoes
Cecilia Cormick, Adrián A. Budini
Loschmidt echoes are a well-established method to characterize dynamical properties such as quantum chaos and sensitivity to perturbations. Here we present a straightforward genera…

Hybrid quantum-classical dynamics with stationary thermal states
Adrián A. Budini
Quantum and classical systems can consistently be coupled via non-unitary time-irreversible mechanisms. In this paper we characterize which kind of corresponding dynamics converge…
