Floquet Quasienergy-Resolved Dissipation, Dynamics, and Spectroscopy in Ultrastrong Cavity-QED
Kamran Akbari, Franco Nori, Stephen Hughes
Strong periodic driving of cavity-quantum electrodynamics (QED) in the ultrastrong-coupling regime creates nonequilibrium states whose dissipation is governed by Floquet quasienerg…
Spin-Squeezing-Enhanced Charging for Quantum Dicke Batteries
Ke-Xiong Yan, Jia-Wen Yu, Yiming Yu +5
High-power Dicke quantum batteries (QBs) typically exploit collective superradiance, whereas intrinsic matter-matter interactions are conventionally considered detrimental. Here, w…
Qubit Readout via State-Dependent Radiative Linewidths
Yiming Yu, Xinyu Zhao, Jia-Wen Yu +5
Fast qubit readout conventionally encodes state information in a dispersive frequency shift. Here we formulate a linewidth-encoded quantum non-demolition measurement channel in whi…
Anisotropic Rabi Model as a Noise Biased Qubit
Jia-Wen Yu, Ke-Xiong Yan, Yuan Qiu +7
We present the quantum anisotropic Rabi model as a potential resource for a noise biased qubit. The system-environment coupling can be biased by tuning the relative strengths of th…
Strongly-coupled non-Markovian waveguide QED with input-output HEOM
Neill Lambert, Yi-Te Huang, Yueh-Nan Chen +2
We consider the problem of modeling a single qubit in contact with a one-dimensional waveguide beyond the standard perturbative and Markovian approximations. Using the recently dev…
Optical Neural Networks from Coherent Transient Dynamics in Waveguide QED
Jiande Cao, Yexiong Zeng, Franco Nori +1
Optical neural networks promise ultrafast, low-energy information processing by performing computation directly with photons. Current implementations, however, are largely restrict…
Exceptional Point Superradiant Lasing with Ultranarrow Linewidth
Min Du, Qian Bin, Qing-Yang Qiu +2
Achieving superradiant lasing with an ultranarrow linewidth is crucial for enhancing atomic clock stability in quantum precision measurement. By employing the exceptional point (EP…
Cavity QED based on strongly localized modes: exponentially enhancing single-atom cooperativity
Qian Bin, Ying Wu, Jin-Hua Gao +3
Large single-atom cooperativity in quantum systems is important for quantum information processing. Here, we propose to exponentially enhance the single-atom cooperativity paramete…
Theory of multi-qubit superradiance in a waveguide in the presence of finite delay times
Sofia Arranz Regidor, Franco Nori, Stephen Hughes
We study the quantum dynamics of multiple two-level atoms (qubits) in a waveguide quantum electrodynamics system, with a focus on modified superradiance effects between two or four…
Suppressed Energy Relaxation in the Quantum Rabi Model at the Critical Point
Ye-Hong Chen, Zhi-Cheng Shi, Yu-Ran Zhang +2
We derive a modified master equation for the quantum Rabi model in the parameter regime where quantum criticality can occur. The modified master equation can avoid some unphysical…
Floquet engineering the quantum Rabi model in the ultrastrong coupling regime
Kamran Akbari, Franco Nori, Stephen Hughes
We study the quantum Rabi model for a two-level system coupled to a quantized cavity mode under periodic modulation of the cavity-dipole coupling in the ultrastrong coupling regime…
