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.…
Time-dependent self-trapping of Bose-Einstein Condensates in a double-well potential
B. Cui, L. C. Wang, X. X. Yi
Based on the mean-field approximation and the phase space analysis, we discuss the dynamics of Bose-Einstein condensates in a double-well potential. By applying a periodic modulati…
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…
