Robust single-qubit gates by composite pulses in three-level systems
Zhi-Cheng Shi, Hai-Ning Wu, Li-Tuo Shen +3
Composite pulses are an efficient tool for robust quantum control. In this work, we derive the form of the composite pulse sequence to implement robust single-qubit gates in a thre…
Manifestation of classical nonlinear dynamics in optomechanical entanglement with a parametric amplifier
Chang-Sheng Hu, Li-Tuo Shen, Zhen-Biao Yang +3
Cavity optomechanical system involving an optical parametric amplifier (OPA) can exhibit rich classical and quantum dynamical behaviors. By simply modulating the frequency of the l…
Generation and stabilization of entangled coherent states for the vibrational modes of a trapped ion
Zhi-Rong Zhong, Xin-Jie Huang, Zhen-Biao Yang +2
We propose a scheme for preparation of entangled coherent states for the motion of an ion in a two-dimensional anisotropic trap. In the scheme, the ion is driven by four laser beam…
Quantum state engineering by periodical two-step modulation in atomic system
Zhi-Cheng Shi, Du Ran, Li-Tuo Shen +2
By periodical two-step modulation, we demonstrate that the dynamics of multilevel system can still evolve even in multiple large detunings regime, and provide the effective Hamilto…
Dissipative entanglement preparation via Rydberg antiblockade and Lyapunov control
Zong-Xing Ding, Chang-Sheng Hu, Li-Tuo Shen +3
Preparation of entangled steady states via dissipation and pumping in Rydberg atoms has been recently found to be useful for quantum information processing. The driven-dissipative…
Robust Rydberg gate via Landau-Zener control of Förster resonance
Xi-Rong Huang, Zong-Xing Ding, Chang-Sheng Hu +4
In this paper, we propose a scheme to implement the two-qubit controlled-Z gate via the Stark-tuned Förster interaction of Rydberg atoms, where the Förster defect is driven by a ti…
