Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Decoherence in a fermion environment: Non-Markovianity and Orthogonality Catastrophe
F. Plastina, A. Sindona, J. Goold +2
We analyze the non-Markovian character of the dynamics of an open two-level atom interacting with a gas of ultra-cold fermions. In particular, we discuss the connection between the…
Geometrical characterization of non-Markovianity
S. Lorenzo, F. Plastina, M. Paternostro
We introduce a new tool for the quantitative characterisation of the departure form Markovianity of a given dynamical process. Our tool can be applied to a generic -level system…
Routing quantum information in spin chains
Simone Paganelli, Salvatore Lorenzo, Tony J. G. Apollaro +2
Two different models for performing efficiently routing of a quantum state are presented. Both cases involve an XX spin chain working as data bus and additional spins that play the…
