In this contribution, we show that the use of conditional measurements in the resonant interaction of two quantized electromagnetic fields gives rise to nonclassical multiphoton processes. Furthermore, we demonstrate that this phenomenon may enable a robust integrated-optics protocol to engineer quantum states containing a high number of photons, thus making it a potentially appealing platform for exploring mesoscopic quantum phenomena.

通过两场相互作用条件测量的多光子过程

在这个贡献中，我们表明在两个量子化电磁场的共振相互作用中使用条件测量会产生非经典的多光子过程。此外，我们证明这种现象可以使强大的集成光学协议能够设计包含大量光子的量子态，从而使其成为探索介观量子现象的潜在有吸引力的平台。
