论文摘要
挤压光是一种量子资源，可以提高光学测量的灵敏度。但是，现有的挤压光源通常需要高功率，并且不适合便携性。在这里，我们从理论上研究了一种替代技术，用于在原子蒸气中使用简并混合混合产生挤压。我们表明，通过最大程度地减少多余的噪声，该技术有可能在小型二极管激光器上实现的低功率产生可测量的挤压。我们建议采用实验技术来减少多余的噪声，并采用这种替代性非线性光学过程来建立紧凑的低功率挤压光源。
Squeezed light is a quantum resource that can improve the sensitivity of optical measurements. However, existing sources of squeezed light generally require high powers and are not amenable to portability. Here we theoretically investigate an alternative technique for generating squeezing using degenerate four-wave-mixing in atomic vapors. We show that by minimizing excess noise, this technique has the potential to generate measurable squeezing with low powers attainable by a small diode laser. We suggest experimental techniques to reduce excess noise and employ this alternative nonlinear optical process to build a compact, low-power source of squeezed light.
