Cai-Hong Liao, Yan-Ling Li, Long Huang +1
High-precision quantum parameter estimation is fundamental to the advancement of quantum metrology. Although reservoir engineering provides a powerful approach to improve estimatio…
Dual Role of Squeezed-Reservoir in Quantum Phase Synchronization: Boosting and Blockade
Xing Xiao, Tian-Xiang Lu, Wo-Jun Zhong +1
This study explores the dual role of a squeezed reservoir in controlling the quantum phase synchronization of a driven two-level system. We first demonstrate, through a Liouvillian…
Resource-Efficient Teleportation of High-Dimensional Quantum Coherence via Initial Phase Engineering
Long Huang, Cai-Hong Liao, Yan-Ling Li +1
High-dimensional quantum systems leverage an expanded Hilbert space to enhance resilience against decoherence and noise. However, standard quantum teleportation is fundamentally li…
Limitations of strong coupling in non-Markovian quantum thermometry
Qing-Shou Tan, Yang Liu, Xulin Liu +3
We investigate quantum thermometry using a single-qubit probe embedded in a non-Markovian environment, employing the numerically exact hierarchical equations of motion (HEOM) to ov…
SU(2) symmetry of spatiotemporal Gaussian modes propagating in the isotropic dispersive media
Fangqing Tang, Xing Xiao, Lixiang Chen
The far-field intensity distribution of spatiotemporal Laguerre-Gaussian (STLG) modes propagating in free space exhibits a multi-petal pattern analogous to that observed in tilted…
Enhanced high-dimensional teleportation in correlated amplitude damping noise by weak measurement and environment-assisted measurement
Xing Xiao, Tian-Xiang Lu, Yan-Ling Li
High-dimensional teleportation provides various benefits in quantum networks and repeaters, but all these advantages rely on the high-quality distribution of high-dimensional entan…
