可见光光子计数器（VLPC）具有区分光子数状态的能力，与只能检测光子存在或不存在的常规光子计数器形成对比。我们使用这种能力，沿着的过程中的参数下转换，产生光子数态。我们实验证明产生的状态包含1，2，3和4个光子的高保真度。然后，我们探索的VLPC的检测效率的产生率和保真度的创建状态的效果。
The visible light photon counter (VLPC) has the capability to discriminate photon number states, in contrast to conventional photon counters which can only detect the presence or absence of photons. We use this capability, along with the process of parametric down-conversion, to generate photon number states. We experimentally demonstrate generation of states containing 1, 2, 3 and 4 photons with high fidelity. We then explore the effect the detection efficiency of the VLPC has on the generation rate and fidelity of the created states.
