Dynamical multipartite entanglement in a generalized Tavis-Cummings model with XY spin interaction
Yuguo Su, Zhijie Sun, Yiying Yan +5
Multipartite entanglement is a long-term pursuit in the resource theory, offering a potential resource for quantum metrology. Here, we present the dynamical multipartite entangleme…
Spin squeezing and concurrence under Lee-Yang dephasing channels
Yuguo Su, Hongbin Liang, Xiaoguang Wang
The Lee-Yang zeros are one-to-one mapping to zeros in the coherence of a probe spin coupled to a many-body system. Here, we study the spin squeezing under two different types of Le…
Multiple-parameter estimation in a sagnac interferometer
Xu Yu, Hongbin Liang, Xiaoguang Wang
We explored the general characteristics of a Sagnac interferometer in a multiparameter estimation process. We find that in the two-parameter estimation scenario, one cannot make bo…
Majorana stellar representation for mixed-spin systems
Yuguo Su, Fei Yao, Yanming Che +2
By describing the evolution of a quantum state with the trajectories of the Majorana stars on a Bloch sphere, Majorana's stellar representation provides an intuitive geometric pers…
Enhancing the sensitivity of rotation in a multi-atom Sagnac interferometer
Fei Yao, Yanming Che, Yuguo Su +3
We investigate quantum sensing of rotation with a multi-atom Sagnac interferometer and present multi-partite entangled states to enhance the sensitivity of rotation frequency. For…
Phase-space geometric Sagnac interferometer for rotation sensing
Yanming Che, Fei Yao, Hongbin Liang +2
Quantum information processing with geometric features of quantum states may provide promising noise-resilient schemes for quantum metrology. In this work, we theoretically explore…
Magnetotransport properties of the type II Weyl semimetal candidate Ta3S2
D. Chen, L. X. Zhao, J. B. He +8
We have investigated the magnetoresistance (MR) and Hall resistivity properties of the single crystals of tantalum sulfide, Ta3S2, which was recently predicted to be a new type II…
