Tracking quantum state evolution by the Berry curvature with a two-level system
Ze-Lin Zhang, Ping Xu, Zhen-Biao Yang
We investigate two kinds of topological structures (sphere and torus) spanned by the controlled parameters of a driven two-level system's Hamiltonian, and consider the connection b…
Manipulating complex hybrid entanglement and testing multipartite Bell inequalities in a superconducting circuit
Yuwei Ma, Xiaoxuan Pan, Weizhou Cai +9
Quantum correlations in observables of multiple systems not only are of fundamental interest, but also play a key role in quantum information processing. As a signature of these co…
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…
Deterministic entanglement swapping in a superconducting circuit
Wen Ning, Xin-Jie Huang, Pei-Rong Han +8
Entanglement swapping, the process to entangle two particles without coupling them in any way, is one of the most striking manifestations of the quantum-mechanical nonlocal charact…
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…
