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…
Critical sensing with a single bosonic mode without boson-boson interactions
Ken Chen, Jia-Hao Lü, Xin Zhu +4
Critical phenomena of quantum systems are useful for enhancement of quantum sensing. However, experimental realizations of criticality enhancement have been confined to very few sy…
Criticality-Enhanced Quantum Sensing in the Anisotropic Quantum Rabi Model
Xin Zhu, Jia-Hao Lü, Wen Ning +4
Quantum systems that undergo quantum phase transitions exhibit divergent susceptibility and can be exploited as probes to estimate physical parameters. We generalize the dynamic fr…
Critical quantum sensing based on the Jaynes-Cummings model with a squeezing drive
Jia-Hao Lü, Wen Ning, Xin Zhu +4
Quantum sensing improves the accuracy of measurements of relevant parameters by exploiting the unique properties of quantum systems. The divergent susceptibility of physical system…
Beating the break-even point with a discrete-variable-encoded logical qubit
Zhongchu Ni, Sai Li, Xiaowei Deng +12
Quantum error correction (QEC) aims to protect logical qubits from noises by utilizing the redundancy of a large Hilbert space, where an error, once it occurs, can be detected and…
Exceptional entanglement phenomena: non-Hermiticity meeting non-classicality
Pei-Rong Han, Fan Wu, Xin-Jie Huang +11
Non-Hermitian (NH) extension of quantum-mechanical Hamiltonians represents one of the most significant advancements in physics. During the past two decades, numerous captivating NH…
