论文摘要
在这项研究中，我们探讨了纠缠多模式挤压光的理论应用，用于无标签的光学超分辨率成像。通过使用单模挤压光输入来生成大量纠缠的多模式通过一系列平衡的梁拆分器挤压光线，我们创建了一个多模式量子光状态，其出色的纠缠和噪声抑制在射击噪声水平以下。与经典相干状态光成像相比，当成像样品中使用相同数量的光子时，这显着降低了成像测量误差。我们演示了如何优化成像系统的参数以实现Heisenberg成像误差限制，并考虑到纠缠模式和所使用的光子的数量。我们还检查了成像系统中光损失的影响，需要根据光损耗的程度对优化参数进行调整。在实际应用中，这种新的量子成像方法与使用非输入，无斑点的连贯状态光相比，将实现相同图像质量的光子数量减少了两个数量级。
In this study, we explore the theoretical application of entangled multi-mode squeezed light for label-free optical super-resolution imaging. By generating massively entangled multi-mode squeezed light through an array of balanced beam splitters, using a single-mode squeezed light input, we create a multi-mode quantum light state with exceptional entanglement and noise suppression below the shot noise level. This significantly reduces imaging measurement errors compared to classical coherent state light imaging when the same number of photons are used on the imaging sample. We demonstrate how to optimize the imaging system's parameters to achieve the Heisenberg imaging error limit, taking into account the number of entangled modes and photons used. We also examine the effects of optical losses in the imaging system, necessitating adjustments to the optimized parameters based on the degree of optical loss. In practical applications, this new quantum imaging approach reduces the number of photons needed to achieve the same image quality by two orders of magnitude compared to classical imaging methods that use non-entangled, non-squeezed coherent state light.
