Critical quantum geometric tensors of parametrically-driven nonlinear resonators
Hao-Long Zhang, Jia-Hao Lv, Ken Chen +4
Parametrically driven nonlinear resonators represent a building block for realizing fault-tolerant quantum computation and are useful for critical quantum sensing. From a fundament…
Bulk-boundary correspondence in topological systems with the momentum dependent energy shift
Huan-Yu Wang, Zhen-Biao Yang, Wu-Ming Liu
Bulk-boundary correspondences (BBCs) remain the central topic in modern condensed matter physics, and are gaining increasing interests with the recent discovery of non-Hermitian sk…
Quantum metric and metrology with parametrically-driven Tavis-Cummings models
Jia-Hao Lü, Pei-Rong Han, Wen Ning +5
We study the quantum metric in a driven Tavis-Cummings model, comprised of multiple qubits interacting with a quantized photonic field. The parametrical driving of the photonic fie…
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…
