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…
Neural Network-Based Design of Approximate Gottesman-Kitaev-Preskill Code
Yexiong Zeng, Wei Qin, Ye-Hong Chen +2
Gottesman-Kitaev-Preskill (GKP) encoding holds promise for continuous-variable fault-tolerant quantum computing. While an ideal GKP encoding is abstract and impractical due to its…
Spontaneous emission in Casimir-Rabi oscillations through a weak optomechanical coupling
Ke-Xiong Yan, Yuan Qiu, Yang Xiao +3
The dynamical Casimir effect (DCE) describes the energy conversion from a mechanical motion to the electromagnetic fields. When the mechanical oscillator is in a mechanically excit…
Preparation of high fidelity entangled cat states with composite pulses
Ge-Ge Gu, Dong-Sheng Li, Ye-Hong Chen +2
We propose a protocol for the preparation of high-fidelity entangled cat states with composite pulses. The physical model contains two Kerr-nonlinear resonators and a cavity. By pr…
Generating three-photon Rabi oscillations without a large-detuning condition
Ke-Xiong Yan, Yuan Qiu, Yang Xiao +2
It is well known that in the quantum Rabi model, a three-photon resonance occurs when the cavity field bare frequency is about 1/3 of the atomic transition frequency. In this manus…
Optimally robust shortcuts to population inversion in cat-state qubits
Shao-Wei Xu, Zhong-Zheng Zhang, Yue-Ying Guo +2
Cat-state qubits formed by photonic coherent states are a promising candidate for realizing fault-tolerant quantum computing. Such logic qubits have a biased noise channel that the…
Error-Tolerant Amplification and Simulation of the Ultrastrong-Coupling Quantum Rabi Model
Ye-Hong Chen, Zhi-Cheng Shi, Franco Nori +1
Cat-state qubits formed by photonic cat states have a biased noise channel, i.e., one type of error dominates over all the others. We demonstrate that such biased-noise qubits are…
