Beam-splitting photon number resolved (PNR) detection is one of the typical non-Gaussian operations in quantum optics. In this paper, we show that, by such an operation, the antibunching light can be generated by performing the beam-splitting PNR measurements of the superbunching squeezed vacuum light to subtract the odd photons. This is because that the squeezed vacuum is superposed by the even-photon Fock states, while its odd-photons subtracted state is just superposed by the odd-photon Fock states and the superposed probability of the single-photon state is significantly high. Hopefully, beam-splitting PNR detection could also be used to implement other desired non-Gaussian operations for engineering various nonclassical light, as the PNR detectors have been well developed in recent years.

分束光子数分辨（PNR）检测是量子光学中典型的非高斯操作之一。在本文中，我们表明，通过这种操作，可以通过对超束压缩真空光进行分束PNR测量以减去奇数光子来生成反束光。这是因为被压缩的真空被偶光子Fock状态叠加，而其奇光子减法状态仅被奇光子Fock状态叠加，并且单光子状态的叠加概率非常高。有希望的是，分束式PNR检测器还可用于实现其他所需的非高斯操作，以对各种非经典光进行工程设计，因为PNR检测器在最近几年得到了很好的开发。
