Periodic dynamics in an Ising chain with a quadratic transverse field
H. P. Zhang, Z. Song
A quadratic well plays a central role in a wide variety of modern physical theories and applications. In this work, we investigate many-body dynamics in a quadratic well, using an…
Quantum relaxometry for detecting biomolecular interactions with single NV centers
Min Li, Qi Zhang, Xi Kong +14
The investigation of biomolecular interactions at the single-molecule level has emerged as a pivotal research area in life science, particularly through optical, mechanical, and el…
Identifying the -qubit state with quantum uncertainty relation
Zhi-Jie Liu, Hao-Nan Qiang, Jie Zhou +2
The state, a canonical representative of multipartite quantum entanglement, plays a crucial role in quantum information science due to its robust entanglement properties. Quant…
Classical and Quantum Resources in Perfect Teleportation
Zhu Dian, Fulin Zhang, Jingling Chen
We propose a teleportation protocol that enables perfect transmission of a qubit using a partially entangled two-qutrit quantum channel. Within our scheme, we analyze the relations…
Expedited thermalization dynamics in incommensurate systems
Mingdi Xu, Zijun Wei, Xiang-Ping Jiang +1
We study the thermalization dynamics of a quantum system embedded in an incommensurate potential and coupled to a Markovian thermal reservoir. The dephasing induced by the bath dri…
Hierarchic superradiant phases in anisotropic Dicke model
D. K. He, Z. Song
We revisit the phase diagram of an anisotropic Dicke model by revealing the non-analyticity induced by underlying exceptional points. We find that, from a dynamical perspective, th…
