------------------------------------------------------------Deterministic and programmable frequency-bin quantum gates via cavity-assisted sum-frequency generationMATLAB Code Package------------------------------------------------------------ This package contains the MATLAB scripts used to generate the numericalresults and figure datas in the paper: “Deterministic and programmable frequency-bin quantum gates via cavity-assisted sum-frequency generation” **Author**: Xin Chen **Contact**: chenxin@qzc.edu.cn The code simulates cavity-assisted sum-frequency generation (SFG) andevaluates gate-performance metrics including: • Amplitude of the transfer function for the CSFG process • Photon-counting (PC) fidelity and conversion efficiency (CE) • Homodyne-detection (HD) fidelity and CE • Full-matrix (FM) fidelity and CE • Control-mode spectral sensitivity (indistinguishability vs γ/Δω)
