AI 中文摘要
本文开发了一种光学可移动的里德堡原子量子接收机（RAQR），其中探测光和耦合光在每个蒸汽池内被操控，无需机械驱动即可动态重构有效射频（RF）感知位置。通过将原子转换系数、光学操控相位和池中心阵列响应分离为不同因子，推导得到闭式等效基带模型，并针对林德布洛德主方程的数值解验证了该模型的准确性。基于推导的模型，揭示了两种互补的信道成形机制，包括通过射频到光学转换实现的固有波束图成形，以及通过光学位移实现的单池相位控制。为进一步利用这些能力，针对光学位置和本振设计构建了非凸和速率最大化问题，并通过带解析梯度的交替优化框架求解。仿真结果验证了推导的模型，并展示了光学可移动性带来的显著性能提升，凸显了其作为未来无线网络可编程接收机架构的潜力。
英文摘要
This paper develops an optically movable Rydberg atomic quantum receiver (RAQR), in which the probe and coupling beams are steered within each vapor cell to dynamically reconfigure the effective radio-frequency (RF) sensing position without mechanical actuation. A closed-form equivalent baseband model is derived by separating the atomic transduction coefficient, optical steering phase, and cell-center array response into distinct factors and the accuracy of the resulting model is validated against numerical solutions of the Lindblad master equation. Based on the derived model, we reveal two complementary channel-shaping mechanisms, including intrinsic beam-pattern shaping through RF-to-optical transduction and per-cell phase control enabled by optical displacement. To further exploit these capabilities, a non-convex sum-rate maximization problem is formulated over the optical positions and local oscillator design and solved via an alternating optimization framework with analytical gradients. Simulation results validate the derived model and demonstrate substantial performance gains enabled by optical movability, highlighting its potential as a programmable receiver architecture for future wireless networks.
