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…
Efficient and flexible preparation of photonic NOON states in a superconducting system
Dong-Sheng Li, Yi-Hao Kang, Zhi-Cheng Shi +3
The NOON states play a critical role as physical resources in quantum information processing and quantum metrology, yet their preparation efficiency and applicability are often con…
Noise-resilient nonadiabatic geometric quantum computation for bosonic binomial codes
Dong-Sheng Li, Yang Xiao, Yu Wang +5
The binomial code is renowned for its parity-mediated loss immunity and loss-error recoverability, while geometric phases are widely recognized for their intrinsic resilience again…
Controllable Non-Hermitianity in Continuous-Variable Qubits
Ke-Xiong Yan, Zhi-Cheng Shi, Ye-Hong Chen +1
Pure dephasing is the dominant leak mechanism in photonic cat qubits because its phase errors disrupt the parity protection, rendering the qubit vulnerable to energy relaxation. In…
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…
