我们采用马赫-曾德尔配置的滤波场形式主义，从理论上研究了声调制量子点的共振荧光光谱中的边带间相位相干性。我们证明，干涉图的几何倾斜是相位相干性的指标，对环境白噪声具有鲁棒性。具体而言，噪声诱导的光谱扩散会降低整体条纹强度，但会使特征倾斜严格保持不变。我们的发现建立了一个用于验证光谱边带之间单光子相干性的框架，这对于实际嘈杂的固态架构中的频率-bin编码和可扩展量子网络至关重要。
英文摘要
We theoretically investigate the inter-sideband phase coherence within the resonance fluorescence spectrum of an acoustically modulated quantum dot using a filtered-field formalism for a Mach-Zehnder configuration. We demonstrate that geometric slant of the interferograms provides an indicator of phase coherence that is resilient to environmental white noise. Specifically, noise-induced spectral diffusion reduces the global fringe intensity, while leaving the characteristic inclination strictly invariant. Our findings establish a framework for verifying single-photon coherence between spectral sidebands, essential for frequency-bin encoding and scalable quantum networking in realistic, noisy solid-state architectures.
