Open system quantum dynamics with correlated initial states, not completely positive maps and non-Markovianity
quantum dynamics non-Markovianity Quantum Physics
2010/11/8
Dynamical A and B maps have been employed extensively by Sudarshan and co-workers to investigate open system evolution of quantum systems. A canonical structure of the A-map is introduced here. It is ...
Initial correlations in open system's dynamics: The Jaynes-Cummings model
Initial correlations open system's dynamics Jaynes-Cummings model
2010/11/8
Employing the trace distance as a measure for the distinguishability of quantum states, we study the influence of initial correlations on the dynamics of open systems. We concentrate on the Jaynes-Cu...
Quantum chaos of a mixed, open system of kicked cold atoms

We suggest and demonstrate an all-optical experimental setup to observe and engineer entanglement oscillations of a pair of polarization qubits in a non-Markovian channel. We generate entangled photon...
On the Contractivity of Hilbert-Schmidt distance under open system dynamics
Hilbert-Schmidt distance system dynamics
2010/4/12
We show that the Hilbert-Schmidt distance, unlike the trace distance, between quantum states is generally not monotonic for open quantum systems subject to Lindblad semigroup dynamics. Sufficient cond...
Dynamics of entanglement in Two-Qubit Open System Interacting with a Squeezed Thermal Bath via Dissipative interaction
Dynamics of entanglement Two-Qubit Open System Squeezed Thermal Bath Dissipative interaction
2010/4/7
We study the dynamics of entanglement in a two-qubit system interacting with a squeezed thermal bath via a dissipative system-reservoir interaction with the system and reservoir assumed to be in a sep...
