Nonreciprocal Entanglement by Dynamically Encircling a Nexus
Lei Huang, Peng-Fei Wang, Jian-Qi Zhang +5
Nonreciprocal entanglement, characterized by inherently robust operation, is a cornerstone for quantum information processing and communications. However, it remains a great challe…
Sideband Cooling of a Trapped Ion in Strong Sideband Coupling Regime
Shuo Zhang, Zhuo-Peng Huang, Tian-Ci Tian +4
Conventional theoretical studies on the ground-state laser cooling of a trapped ion have mostly focused on the weak sideband coupling (WSC) regime, where the cooling rate is invers…
Ramsey Interferometry based on stimulated Brillouin scattering
Xian-Fu Quan, Zhi-Rui Gong, Shuo Zhang +3
Realizing highly sensitive interferometry is essential to accurate observation of quantum properties. Here we study two kinds of Ramsey interference fringes in a whispering-gallery…
Double-passage ground-state cooling induced by quantum interference in the hybrid optomechanical system
Lingchao Li, Longjiang Liu, Shuo Zhang +2
We propose a quantum interference cooling scheme for a nano-mechanical resonator (NAMR) in a hybrid optomechanical system, where the atoms are trapped in an optomechanical cavity,…
