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…
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…
Rydberg-interaction gates via adiabatic passage and phase control of driving fields
Huaizhi Wu, Xi-Rong Huang, Chang-Sheng Hu +2
In this paperwe propose two theoretical schemes for implementation of quantum phase gates by engineering the phase-sensitive dark state of two atoms subjected to Rydberg-Rydberg in…
Twofold mechanical squeezing in a cavity optomechanical system
Chang-Sheng Hu, Zhen-Biao Yang, Huaizhi Wu +2
We investigate the dynamics of an optomechanical system where a cavity with a movable mirror involves a degenerate optical parametric amplifier and is driven by a periodically modu…
