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…
Parallel Segment Entanglement Swapping
Binjie He, Seng W. Loke, Dong Zhang
In the noisy intermediate-scale quantum era, scientists are trying to improve the entanglement swapping success rate by researching anti-noise technology on the physical level, the…
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…
Topological Transitions in a Kerr Nonlinear Oscillator
Juan Lin, Shou-Bang Yang, Fan Wu +1
A Kerr nonlinear oscillator (KNO) supports a pair of steady eigenstates, coherent states with opposite phases, that are good for the encoding of continuous variable qubit basis sta…
Scheme for measuring topological transitions in a continuous variable system
Bi-Yao Wang, Hao-Long Zhang, Shou-Bang Yang +3
We propose a scheme for measuring topological properties in a two-photon-driven Kerr-nonlinear resonator (KNR) subjected to a single-photon modulation. The topological properties a…
