论文摘要
基于对六端口的Mach-Zehnder干涉仪的预言干扰，我们提出了协议，以在主要输出端口中生成一系列多光子状态，通过在主输入端口中注入连贯的状态，在两个辅助输入端口中注入两个Fock状态，并在两个辅助输出端口中测量两个Fock状态。只有在所有辅助端口中的单个光子级（即| 0>或| 1>）上操纵，我们生成了16种类型（六个类别）的多光顿非分类状态，其状态向量被统一为新的相干状态的叠加，一个新的相干状态，一个单photon添加了相似的状态，并添加了一个coherent cooherent state，又添加了一个彼此的同伴。实际上，可以通过调节相互作用参数（包括连贯的场强和偏移阶段）来创建广泛的非古典现象。我们主要分析我们所有考虑的状态的正交形式效应。特别有趣的是，至少在目前的情况下，最大挤压最高为2.57db，成功概率为6.7％。
Based on heralded interference on a six-port Mach-Zehnder interferometer, we propose protocols to generate a series of multiphoton states in primary output port, by injecting a coherent state in primary input port and two Fock states in two ancillary input ports, and measuring two Fock states in two ancillary output ports. Only manipulating at the single-photon level (i.e, |0> or |1>) in all ancillary ports, we generate sixteen types (six categories) of multiphoton nonclassical states, whose state vectors are unified as superposition of a new coherent state, a single-photon added coherent state, and a two-photon added coherent state. Indeed, a wide range of nonclassical phenomena can be created by modulating the interaction parameters (including coherent field strength and shift phase). We mainly analyze quadrature-squeezing effects for all our considered states. Of particular interest is maximum squeezing of up to 2.57dB, with success probability 6.7%, at least in our present cases.
