Experimental preparation and manipulation of squeezed cat states via an all-optical in-line squeezer
Meihong Wang, Miao Zhang, Zhongzhong Qin +5
The squeezed cat state, an essential quantum resource, can be used for quantum error correction and slowing decoherence of the optical cat state. However, preparing a squeezed cat…
Physical interpretation of nonlocal quantum correlation through local description of subsystems
Tanumoy Pramanik, Xiaojiong Chen, Yu Xiang +11
Characterization and categorization of quantum correlations are both fundamentally and practically important in quantum information science. Although quantum correlations such as n…
Generalized gauge transformation with -symmetric non-unitary operator and classical correspondence of non-Hermitian Hamiltonian for a periodically driven system
Yan Gu, Xiao-Lei Hao, J. -Q. Liang
We in this paper demonstrate that the -symmetric non-Hermitian Hamiltonian for a periodically driven system can be generated from a kernel Hamiltonian by a generalized gauge tr…
Gate fidelity, dephasing, and "magic" trapping of optically trapped neutral atom
Pengfei Yang, Gang Li, Zhihui Wang +2
The fidelity of the gate operation and the coherence time of neutral atoms trapped in an optical dipole trap are figures of merit for the applications. The motion of the trapped at…
Learning quantum dissipation by the neural ordinary differential equation
Li Chen, Yadong Wu
Quantum dissipation arises from the unavoidable coupling between a quantum system and its surrounding environment, which is known as a major obstacle in the quantum processing of i…
Characterizing Multipartite Non-Gaussian Entanglement for Three-Mode Spontaneous Parametric Down-Conversion Process
Mingsheng Tian, Yu Xiang, Feng-Xiao Sun +2
Very recently, strongly non-Gaussian states have been observed via a direct three-mode spontaneous parametric down-conversion in a superconducting cavity [Phys. Rev. X 10, 011011 (…
