Bound state in the continuum and multiple atom state transfer applications in a waveguide QED setup
Xiang Guo, Xiaojun Zhang, Mingzhu Weng +5
Bound states in the continuum (BICs) have been extensively exploited to enhance light--matter interactions in metamaterials, yet their emergence and utility in multi-atom waveguide…
Cramér-Rao bound and quantum parameter estimation with non-Hermitian systems
Jianning Li, Haodi Liu, Zhihai Wang +1
The quantum Fisher information constrains the achievable precision in parameter estimation via the quantum Cramér-Rao bound, which has attracted much attention in Hermitian systems…
Witness of topological phase transition and Weyl points in an open topological system
Mingzhu Weng, Weijun Cheng, Zhihai Wang +1
Recently, the tunable Weyl-semimetal bands and the associate topological phase transition have been successfully simulated in superconducting quantum circuits [X. Tan, \textit{et a…
The non-Hermitian geometrical property of 1D Lieb lattice under Majorana's stellar representation
Xingran Xu, Haodi Liu, Zhidong Zhang +1
The topological properties of non-Hermitian Hamiltonian is a hot topic, and the theoretical studies along this research line are usually based on the two-level non-Hermitian Hamilt…
Quantum synchronization of two mechanical oscillators in coupled optomechanical systems with Kerr nonlinearity
Guo-jian Qiao, Hui-xia Gao, Hao-di Liu +1
We investigate the quantum synchronization phenomena of two mechanical oscillators of different frequencies in two optomechanical systems under periodically modulating cavity detun…
Effect of spin relaxations on the spin mixing conductances for a bilayer structure
D. X. Li, H. Z. Shen, H. D. Liu +1
The spin current can result in a spin-transfer torque in the normal-metal(NM)|ferromagnetic-insulator(FMI) or normal-metal(NM)|ferromagnetic-metal(FMM) bilayer. In the earlier stud…
Coherent-State Approach for Majorana representation
H. D. Liu, L. B. Fu, Xiaoguang Wang
By representing a quantum state and its evolution with the majorana stars on the Bloch sphere, the Majorana representation (MR) provide us an intuitive way to study a physical syst…
Non-adiabatic holonomic quantum computation in linear system-bath coupling
Chunfang Sun, Gangcheng Wang, Chunfeng Wu +4
Non-adiabatic holonomic quantum computation in decoherence-free subspaces protects quantum information from control imprecisions and decoherence. For the non-collective decoherence…
