本文建立了海森堡图像框架，用于实现毫米波到光子数据的无缝转导。基于该框架，首次展示了利用数字调制的经典毫米波束对连续变量（CV）量子光学态进行非接触式调制。我们的分析揭示了毫米波相位变化对调制后的光学相干态和压缩态在Wigner空间中演化的直接影响。此外，分析表明，经典毫米波相位不仅控制位移，还调制压缩态的 quadrature 不确定性，从而揭示了一种将信息嵌入到多个量子光学自由度的新技术。这项工作为无需传统片上金属互连和复杂电子控制电路的量子光无线调控奠定了理论和分析基础，从而为集成量子光子学与新兴毫米波或太赫兹通信技术的无缝桥接开辟了关键途径。

英文摘要

This paper establishes the Heisenberg's picture framework for seamless mmWave-to-photonic data transduction. Based on this framework, contactless modulation of continuous-variable (CV) quantum optical states with digitally modulated classical mmWave beams is shown for the first time. Our analysis reveals the direct influence of mmWave phase variation on the Wigner-space evolution of modulated optical coherent and squeezed states. Furthermore, the analysis indicates that classical mmWave phase not only governs the displacement but also modulates the quadrature uncertainty of squeezed states, revealing a novel technique for embedding information onto multiple quantum-optical degrees of freedom. This work builds the theoretical and analytical foundation for wireless conditioning of quantum light without conventional on-chip metallic interconnects and complex electronic control circuitry, thereby opening a key pathway toward seamless bridging of integrated quantum photonics with emerging mmWave or THz communication technology.
