Super-resolution of two unbalanced point sources assisted by the entangled partner
Abdelali Sajia, X. -F. Qian
Sub-diffraction-limit resolution, or super-resolution, had been successfully demonstrated by recent theoretical and experimental studies for two-point sources with ideal equal-brig…
Freezing and Thawing of Entanglement in Lossless Multiparty Systems
X. -F. Qian, C. Qu, J. H. Eberly
Entanglement freezing has been demonstrated existing in various noisy decoherence mechanisms. Here we explore its universality by investigating freezing behavior in a lossless mult…
Driven-dissipative Quantum Dynamics in Cavity Magnon-Polariton System
Guogan Zhao, Yong Wang, X. -F. Qian
The dynamics of arbitrary-order quantum correlations in a cavity magnon-polariton system are investigated based on the quantum master equation in the coherent state representation.…
Quantum criticality of the Ohmic spin-boson model in a high dense spectrum: symmetries,quantum fluctuations and correlations
Xiaohui Qian, Congzhi Zeng, Nengji Zhou
Study of dissipative quantum phase transitions in the Ohmic spin-boson model is numerically challenging in a dense limit of environmental modes. In this work, large-scale numerical…
