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…
