Electromagnetic instability of vacuum with instantons in the holographic plasma
Shao-cheng Hou, Si-wen Li
Using the gauge-gravity duality, we study the electromagnetic instability of vacuum with instantons in holographic plasma. The model we employ is the D(-1)-D3 brane system in which…
Memory effects in a dynamical decoupling process
S. C. Hou, X. Y. Zhang, Si-wen Li +1
We establish a simple quantitative relationship between the environmental memory effects and the characteristics in a dynamical decoupling process. In contrast to previous works, o…
Influence of initial states on memory effects: A study of early-time superradiance
S. C. Hou, G. Q. Shuai, X. Y. Zhang +2
The initial state of a quantum system can significantly influence its future dynamics, especially in non-Markovain quantum processes due to the environmental memory effects. Based…
Bound state and Localization of excitation in many-body open systems
H. T. Cui, H. Z. Shen, S. C. Hou +1
Bound state and time evolution for single excitation in one dimensional XXZ spin chain within non-Markovian reservoir are studied exactly. As for bound state, a common feature is t…
Non-Markovianity and memory effects in quantum open systems
S. C. Hou, S. L. Liang, X. X. Yi
Although a number of measures for quantum non-Markovianity have been proposed recently, it is still an open question whether these measures directly characterize the memory effect…
Preparation of edge states by shaking boundaries
Z. C. Shi, S. C. Hou, L. C. Wang +1
Preparing topological states of quantum matter, such as edge states, is one of the most important directions in condensed matter physics. In this work, we present a proposal to pre…
Realization of quantum gates by Lyapunov control
S. C. Hou, L. C. Wang, X. X. Yi
We propose a Lyapunov control design to achieve specific (or a family of) unitary time-evolution operators, i.e., quantum gates in the Schrödinger picture by tracking control. Two…
Optimal Lyapunov quantum control on two-level systems: convergence and extended techniques
L. C. Wang, S. C. Hou, X. X. Yi +2
Taking a two-level system as an example, we show that a strong control field may enhance the efficiency of optimal Lyapunov quantum control in [Hou et al., Phys. Rev. A \textbf{86}…
Single photon reflection and transmission in optomechanical system
M. A. Khan, S. C. Hou, K. Farooq +1
Cavity Optomechanical system is speedily approaching the regime where the radiation pressure of a single photon displaces the moving mirror. In this paper, we consider a cavity opt…
Optimal Lyapunov-based quantum control for quantum systems
S. C. Hou, M. A. Khan, Daoyi Dong +2
Quantum Lyapunov control was developed in order to transform a quantum system from arbitrary initial states to a target state. The idea is to find control fields that steer the Lya…
Singularity of dynamical maps
S. C. Hou, X. X. Yi, S. X. Yu +1
For a dynamical map , which sends a state of quantum open system to a state , the decomposition law may break down at a sp…
An alternative non-Markovianity measure by divisibility of dynamical map
S. C. Hou, X. X. Yi, S. X. Yu +1
Identifying non-Markovianity with non-divisibility, we propose a measure for non-Markovinity of quantum process. Three examples are presented to illustrate the non-Markovianity, me…
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.…
Adiabatic evolution under quantum control
W. Wang, S. C. Hou, X. X. Yi
One of the difficulties in adiabatic quantum computation is the limit on the computation time. Here we propose two schemes to speed-up the adiabatic evolution. To apply this contro…
