Implementation and topological characterization of Weyl exceptional rings in quantum-mechanical systems
Hao-Long Zhang, Pei-Rong Han, Xue-Jia Yu +8
Non-Hermiticity can lead to the emergence of many intriguing phenomena that are absent in Hermitian systems, enabled by exceptional topological defects, among which Weyl exceptiona…
Open system geometric phase based on system-reservoir joint state evolution
Shi-Biao Zheng
The geometric phase is of fundamental interest and plays an important role in quantum information processing. However, the definition and calculation of this phase for open systems…
Single-step implementation of a multiple-target-qubit controlled phase gate without need of classical pulses
Chui-Ping Yang, Qi-Ping Su, Feng-Yang Zhang +1
We propose a simple method for realizing a multiqubit phase gate of one qubit simultaneously controlling target qubits, by using three-level quantum systems (i.e., qutrits) cou…
Electromagnetically induced transparency with controlled van der Waals interaction
Huaizhi Wu, Meng-Meng Bian, Li-Tuo Shen +3
We study the electromagnetically induced transparency (EIT) effect with two individually addressed four-level Rydberg atoms subjected to the interatomic van der Waals interaction.…
Dissipation-induced geometric phase for an atom in cavity QED
Shi-Biao Zheng
We present a feasible scheme to investigate the geometric phase for an atom trapped in an optical cavity induced by the effective decay process due to cavity photon loss. The cavit…
Jaynes-Cummings model with a collective atomic mode
Shi-Biao Zheng
We study the dynamics of a single control atom and an atomic sample interacting with a nonresonant cavity mode. The control atom is driven by an auxiliary classical field. Under ce…
