Shortcuts to adiabaticity for open quantum systems and a mixed-state inverse engineering scheme
S. L. Wu, W. Ma, X. L. Huang +1
We propose a fast mixed-state control scheme to transfer the quantum state along designable trajectories in Hilbert space, which is robust to multiple decoherence noises. Starting…
Adiabatic Decoherence-Free Subspaces and its Shortcuts
S. L. Wu, X. L. Huang, H. Li +1
The adiabatic theorem and "shortcuts to adiabaticity" for the adiabatic dynamics of time-dependent decoherence-free subspaces are explored in this paper. Starting from the definiti…
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…
Dynamics of quantum-classical hybrid system: effect of matter-wave pressure
J. Shen, X. L. Huang, X. X. Yi +2
Radiation pressure affects the kinetics of a system exposed to the radiation and it constitutes the basis of laser cooling. In this paper, we study {\it matter-wave pressure} throu…
Driving Quantum System into Decoherence-free Subspaces by Lyapunov Control
X. X. Yi, X. L. Huang, Chunfeng Wu +1
We present a scheme to drive a finite-dimensional quantum system into the decoherence-free subspaces(DFS) by Lyapunov control. Control fields are established by Lyapunov function.…
Nonequilibrium thermal entanglement in three-qubit model
X. L. Huang, J. L. Guo, X. X. Yi
Making use of the master equation and effective Hamiltonian approach, we investigate the steady state entanglement in a three-qubit model. Both symmetric and nonsymmetric qubi…
Born-Oppenheimer approximation in open systems
X. L. Huang, X. X. Yi
We generalize the standard Born-Oppenheimer approximation to the case of open quantum systems. We define the zeroth order Born-Oppenheimer approximation of an open quantum system a…
