Experimental demonstration of entanglement sudden death induced by natural dissipation
Yan Wang, Hao-Long Zhang, Jia-Hao Lü +5
Any quantum system inevitably interacts with its natural environment, which can be modeled as a Markovian reservoir consisting of a continuum of electromagnetic field modes. The qu…
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-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…
Topological Transitions in a Kerr Nonlinear Oscillator
Juan Lin, Shou-Bang Yang, Fan Wu +1
A Kerr nonlinear oscillator (KNO) supports a pair of steady eigenstates, coherent states with opposite phases, that are good for the encoding of continuous variable qubit basis sta…
Scheme for measuring topological transitions in a continuous variable system
Bi-Yao Wang, Hao-Long Zhang, Shou-Bang Yang +3
We propose a scheme for measuring topological properties in a two-photon-driven Kerr-nonlinear resonator (KNR) subjected to a single-photon modulation. The topological properties a…
