Observation of photonic dynamics in dissipative quantum Rabi models
Wen Ning, Ri-Hua Zheng, Jia-Hao Lü +5
The quantum Rabi model (QRM), composed of a qubit interacting with a quantized photonic field, is a cornerstone of quantum optics. The QRM with dominant unitary dynamics has been d…
Quantum Geometric Tensor and Critical Metrology in the Anisotropic Dicke Model
Xin Zhu, Jia-Hao Lü, Wen Ning +3
We investigate the quantum phase transition in the anisotropic Dicke model through an examination of the quantum geometric tensor of the ground state. In this analysis, two distinc…
Critical quantum metrology robust against dissipation and non-adiabaticity
Jia-Hao Lü, Wen Ning, Fan Wu +6
Critical systems near quantum phase transitions were predicted to be useful for improvement of metrological precision, thanks to their ultra-sensitive response to a tiny variation…
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…
