论文摘要
使用基于Van Cittert-zernike定理的干涉仪阵列进行成像已被广泛用于天文观测中。最近显示，可以在该系统中实现超分辨率，以成像两个弱热点源。使用量子估计理论，我们考虑使用干涉仪阵列解决两个强热点源的横向分离的基本量子限制，并表明该分辨率不受最长基线的限制。我们提出了使用线性束拆分器和光子 - 单数检测的测量技术，以实现我们的界限。我们的结果表明，在干涉仪阵列中可以实现解决两个强度的两个热点源的超分辨率。
Imaging using interferometer arrays based on the Van Cittert-Zernike theorem has been widely used in astronomical observation. Recently it was shown that superresolution can be achieved in this system for imaging two weak thermal point sources. Using quantum estimation theory, we consider the fundamental quantum limit of resolving the transverse separation of two strong thermal point sources using interferometer arrays, and show that the resolution is not limited by the longest baseline. We propose measurement techniques using linear beam splitters and photon-number-resolving detection to achieve our bound. Our results demonstrate that superresolution for resolving two thermal point sources of any strength can be achieved in interferometer arrays.
