Controllable non-Hermitian topology in a dynamically protected cat qubit
Tian-Le Yang, Pei-Rong Han, Zhen-Biao Yang +1
Dissipatively stabilized cat qubits are promising for fault-tolerant quantum information processing, yet their non-Hermitian (NH) spectral topology remains largely unexplored. We u…
Geometric criticality in the driven Jaynes-Cummings model
Ken Chen, Jia-Hao Lv, Hao-Long Zhang +4
When the photonic mode in the Jaynes-Cummings model is driven by an external classical field, the system can undergo the photon-blockade breakdown phase transition at a critical po…
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…
Mixed-State Topology in Non-Hermitian Systems
Shou-Bang Yang, Pei-Rong Han, Wen Ning +3
Non-Hermitian (NH) systems, owing to the existence of exceptional point (or ring and surface), exhibit exotic topological features which are inaccessible in Hermitian systems. Whil…
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…
Observation of the Transition from Reversible to Irreversible Decoherence of Mesoscopic Quantum Superpositions
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,…
A hypersphere-like non-Abelian Yang monopole and its topological characterization
Shou-Bang Yang, Pei-Rong Han, Wen Ning +3
Synthetic monopoles, which correspond to degeneracies of Hamiltonians, play a central role in understanding exotic topological phenomena. Dissipation-induced non-Herminicity (NH),…
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…
An exceptional surface and its topology
Shou-Bang Yang, Pei-Rong Han, Wen Ning +3
Non-Hermitian (NH) systems can display exceptional topological defects without Hermitian counterparts, exemplified by exceptional rings in NH two-dimensional systems. However, exce…
