我们发展了一个通用的理论来描述通过减去一个单光子来操纵光的多模量子态。该理论适用于各种类型的减法方案，与光模式的物理性质、它们的数量或嵌入的量子态无关。我们表明，不同的减法方案可以描述在一个统一的方法，通过表征其内在的减法模式。光子相减后多模量子光的条件态由相减模的数目及其与光模的匹配来定义。我们提出了通过控制减法模式来操纵光态。在多模量子资源上进行光子相减，有望实现全光、多路复用和可扩展的量子信息协议。
We develop a general theory to describe the manipulation of a multimode quantum state of light via the subtraction of a single photon. The theory is applicable for various types of subtraction schemes independent of the physical nature of the light modes, their number or the embedded quantum states. We show that different subtraction schemes can be described in a unified approach through the characterization of their intrinsic subtraction modes. The conditional state of the multimode quantum light after the photon subtraction is defined by the number of subtraction modes and their matching with the light modes. We propose the manipulation of light states by controlling the subtraction modes. Performing a photon subtraction on a multimode quantum resource is promising for the implementation of a number of quantum information protocols in all-optical, multiplexed and scalable way.
