Universal non-Markovianity Detection in Hybrid Open Quantum Systems
Jiří Svozilík, Raúl Hidalgo-Sacoto, Ievgen I. Arkhipov
A universal characterization of non-Markovianity for any open hybrid quantum systems is presented. This formulation is based on the negativity volume of the generalized Wigner func…
