Abstract

We propose how to generate beams with non-zero orbital angular momentum in the microwave domain using atomic vapor medium and coherent control techniques. Our approach utilizes a difference frequency generation process in a centrosymmetric medium in the presence of a DC electric field for frequency conversion and parametric amplification. By employing phase matching conditions and orbital angular momentum conservation, we constructed a Controlled NOT gate using a three-level atomic configuration. By generating Laguerre-Gaussian fields in the microwave domain, we open up novel possibilities for advanced information processing in wireless communication and potential applications in quantum technologies.

微波环境下结构光的产生与控制非门

提出了利用原子蒸汽介质和相干控制技术在微波域中产生非零轨道角动量光束的方法。我们的方法利用在中心对称介质中存在直流电场的差频产生过程进行频率转换和参数放大。利用相位匹配条件和轨道角动量守恒，构造了一个三能级原子构型的可控非门。通过在微波域中产生拉盖尔-高斯场，我们为无线通信中的高级信息处理和量子技术中的潜在应用开辟了新的可能性。
