Generalized trace distance measure connecting quantum and classical non-Markovianity
Steffen Wißmann, Bassano Vacchini, Heinz-Peter Breuer
We establish a direct connection of quantum Markovianity of an open quantum system to its classical counterpart by generalizing the criterion based on the information flow. Here, t…
Determining the squeezing in multimode fields using nonlocal quantum probes
Steffen Wißmann, Heinz-Peter Breuer
We present a scheme allowing to access the squeezing parameter of multimode fields by means of the dynamics of nonlocal quantum probes. The model under consideration is composed of…
Locality and universality of quantum memory effects
B. -H. Liu, S. Wißmann, X. -M. Hu +7
Recently, a series of different measures quantifying memory effects in the quantum dynamics of open systems has been proposed. Here, we derive a mathematical representation for the…
Nonlocal quantum memory effects in a correlated multimode field
Steffen Wißmann, Heinz-Peter Breuer
We review the model of two qubits coupled locally to an environment which consists of nonlocally correlated field modes [Phys. Rev.Lett. 108, 210402 (2012)]. We derive the correct…
Detecting initial system-environment correlations: Performance of various distance measures for quantum states
S. Wissmann, B. Leggio, H. -P. Breuer
We study the time evolution of four distance measures in the presence of initial systemenvironment correlations. It is well-known that the trace distance between two quantum states…
Optimal state pairs for non-Markovian quantum dynamics
Steffen Wissmann, Antti Karlsson, Elsi-Mari Laine +2
We study a recently proposed measure for the quantification of quantum non-Markovianity in the dynamics of open systems which is based on the exchange of information between the op…
