Information Flow, Non-Markovianity and Geometric Phases
S. L. Wu, X. L. Huang, L. C. Wang +1
Geometric phases and information flows of a two-level system coupled to its environment are calculated and analyzed. The information flow is defined as a cumulant of changes in tra…
Suppressing decoherence and improving entanglement by quantum-jump-based feedback control in two-level systems
S. C. Hou, X. L. Huang, X. X. Yi
We study the quantum-jump-based feedback control on the entanglement shared between two qubits with one of them subject to decoherence, while the other qubit is under the control.…
Born-Oppenheimer approximation for open quantum systems within the quantum trajectory approach
X. L. Huang, S. L. Wu, L. C. Wang +1
Based on the quantum trajectory approach, we extend the Born-Oppenheimer (BO) approximation from closed quantum system to open quantum system, where the open quantum system is desc…
Entropy and specific heat for open systems in steady states
X. L. Huang, B. Cui, X. X. Yi
The fundamental assumption of statistical mechanics is that the system is equally likely in any of the accessible microstates. Based on this assumption, the Boltzmann distribution…
