论文摘要
量子照明是在嘈杂的环境中确定对象存在的任务。我们确定在零物体反射率极限的量子照明的最佳连续变量状态。我们证明，最佳单模式状态是一个连贯的状态，而最佳的两个模式状态是两模式挤压 - vacuum状态。我们发现，在非零反射率下，这些探针并不是最佳的，但仍然保持最佳状态。这证明了连续变量平台的可行性，用于实验可访问，接近最佳的量子照明实现。
Quantum illumination is the task of determining the presence of an object in a noisy environment. We determine the optimal continuous variable states for quantum illumination in the limit of zero object reflectivity. We prove that the optimal single mode state is a coherent state, while the optimal two mode state is the two-mode squeezed-vacuum state. We find that these probes are not optimal at non-zero reflectivity, but remain near optimal. This demonstrates the viability of the continuous variable platform for an experimentally accessible, near optimal quantum illumination implementation.
