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…
Quantum metrology via mitigation of single-photon loss using an engineered nonlinear oscillator
Tian-Le Yang, Wen Ning, Zhen-Biao Yang +1
The fragility of quantum metrological advantages under loss remains a major barrier to practical quantum sensing. For a two-photon-driven (TPD) Kerr resonator (TPD-Kerr model) subj…
Quantum-enhanced estimation of signal field amplitudes with critical squeezed states of photonic modes
Ken Chen, Jia-Hao Lv, Wen Ning +2
Critical phenomena of quantum systems offer a promising strategy to improve measurement precision. So far, many criticality-enhanced quantum metrological schemes have been proposed…
Non-Markovian environment induced chaos in optomechanical system
You-Lin Xiang, Xinyu Zhao, Yan Xia
In traditional research, chaos is frequently accompanied by non-linearity, which typically stems from non-linear interactions or external driving forces. However, in this paper, we…
Giant atoms coupled to waveguide: Continuous coupling and multiple excitations
Shiying Lin, Xinyu Zhao, Yan Xia
We propose a stochastic Schrödinger equation (SSE) approach to investigate the dynamics of giant atoms coupled to a waveguide, addressing two critical gaps in existing research, n…
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…
