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…
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…
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…
Nonadiabatic transitions in non-Hermitian -symmetric two-level systems
Jian-Song Pan, Fan Wu
We systematically characterize the dynamical evolution of time-parity (PT )-symmetric two-level systems with spin-dependent dissipations. If the control parameters of the gap are l…
