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…

Amplification of bosonic interactions through squeezing in the presence of decoherence
Ankit Tiwari, Cecilia Cormick, Christian Arenz
We consider the amplification of bosonic interactions through parametric control that implements squeezing along orthogonal quadratures. We show that bosonic interactions described…
