Exceptional phase transition in a single Kerr-cat qubit
Pei-Rong Han, Tian-Le Yang, Wen Ning +4
Exceptional points in non-Hermitian quantum systems give rise to novel genuine quantum phenomena. Recent explorations of exceptional-point-induced quantum phase transitions have ex…
Exploring the topology induced by non-Markovian Liouvillian exceptional points
Hao-Long Zhang, Yan Wang, Wen Ning +6
Non-Hermitian (NH) systems can display exotic topological phenomena without Hermitian counterparts, enabled by exceptional points (EPs). So far, investigations of NH topology have…
Emergence of irreversible decoherence from unitary dynamics
Ri-Hua Zheng, Jia-Hao Lü, Fan Wu +4
The decoherence of superpositions of classically distinguishable states (cat states) is crucial for understanding quantum-to-classical transitions and quantum measurements. So far,…
Observation of photonic dynamics in dissipative quantum Rabi models
Wen Ning, Ri-Hua Zheng, Jia-Hao Lü +5
The quantum Rabi model (QRM), composed of a qubit interacting with a quantized photonic field, is a cornerstone of quantum optics. The QRM with dominant unitary dynamics has been d…
Experimental observation of non-Markovian quantum exceptional points
Hao-Long Zhang, Pei-Rong Han, Fan Wu +3
One of the most remarkable features that distinguish open systems from closed ones is the presence of exceptional points (EPs), where two or more eigenvectors of a non-Hermitian op…
Enhancement of sensitivity near exceptional points in dissipative qubit-resonator systems
Pei-Rong Han, Fan Wu, Xin-Jie Huang +11
Dissipation usually plays a negative role in quantum metrological technologies, which aim to improve measurement precision by leveraging quantum effects that are vulnerable to envi…
