We experimentally demonstrate the generation of multi-photon Fock states with up to three photons in well-defined spatial-temporal modes synchronized with a classical clock. The states are characterized using quantum optical homodyne tomography to ensure mode selectivity. The three-photon Fock states are probabilistically generated by pulsed spontaneous parametric down conversion at a rate of one per second, enabling complete characterization in 12 hours.
我们通过实验证明了在与经典时钟同步的明确定义的时空模式中产生多达三个光子的多光子福克态。使用量子光学零差层析成像对这些态进行表征，以确保模式选择性。三光子福克态通过脉冲自发参量下转换以每秒一个的速率概率性产生，从而能够在12小时内完成完整表征。
