Non-Hermitian topology in a single driven-dissipative Kerr-Cat qubit
Pei-Rong Han, Huiye Qiu, Hao-Long Zhang +3
The intriguing physical phenomena associated with exceptional points have established non-Hermitian physics as a frontier of modern research. Recent investigations have extended no…
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),…
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…
Robustness of entanglement in a non-Hermitian cavity-optomechanical system even away from exceptional points
Jia-Jia Wang, Yu-Hong He, Chang-Geng Liao +2
Quantum physics can be extended into the complex domain by considering non-Hermitian Hamiltonians that are -symmetric. These exhibit exceptional points (EPs) where th…
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…
Characterization of non-Markovianity with maximal extractable qubit-reservoir entanglement
Pei-Rong Han, Fan Wu, Xin-Jie Huang +5
Understanding the dynamical behavior of a qubit in a reservoir is critical to applications in quantum technological protocols, ranging from quantum computation to quantum metrology…
Measuring topological invariants for higher-order exceptional points in quantum three-mode systems
Pei-Rong Han, Wen Ning, Xin-Jie Huang +7
Owing to the presence of exceptional points (EPs), non-Hermitian (NH) systems can display intriguing topological phenomena without Hermitian analogs. However, experimental characte…
