Persistent spin squeezing of dissipative Lipkin-Meshkov-Glick Model embedded in a general thermal environment
Yonghong Ma, Quanzhen Ding, Ting Yu
We investigate spin squeezing for a Lipkin-Meshkov-Glick (LMG) model coupled to a general non-Markovian environment in a finite temperature regime. Using the non-Markovian quantum…

High-dimensional temporal mode propagation in a turbulent environment
Quanzhen Ding, Rupak Chatterjee, Yuping Huang +1
Temporal modes of photonic quantum states provide a new framework to develop a robust free-space quantum key distribution (QKD) scheme in a maritime environment. We show that the h…

Exact coherence dynamics mediated by a single cavity mode in the presence of leakage
Yusui Chen, Quanzhen Ding, Wufu Shi +2
We present a quantum-state-diffusion equation to characterize the dynamics of a generic atomic system coupled to a leaky cavity mode. As quantum resources, the population, the cohe…
