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…
Effects of uncertainties and errors on Lyapunov control
X. X. Yi, B. Cui, Chunfeng Wu +1
Lyapunov control (open-loop) is often confronted with uncertainties and errors in practical applications. In this paper, we analyze the robustness of Lyapunov control against the u…
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.…
Lyapunov Control on Quantum Open System in Decoherence-free Subspaces
W. Wang, L. C. Wang, X. X. Yi
A scheme to drive and manipulate a finite-dimensional quantum system in the decoherence-free subspaces(DFS) by Lyapunov control is proposed. Control fields are established by Lyapu…
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…
