摘要:

增加量子光子器件的复杂性对于许多光学信息处理应用来说是必不可少的,以达到超越经典模拟的范围,集成光子学已成为实现这一目标的领先平台。在这里,我们展示了三光子量子操作的集成设备包含三个耦合干涉仪,八个空间模式和许多经典和非经典的干扰。这是一个关键的进步,超过以前的复杂性和第一个芯片上的非经典干涉超过两个光子输入。我们引入了一个新的方案来验证量子行为,使用经典的特点的设备元素和层次的光子关联函数。我们准确地预测了设备的量子行为,并显示操作与经典和双可分离的量子模型不一致。这种验证多光子量子行为的方法对于实现增加的电路复杂性至关重要。我们的实验为下一代集成光子量子模拟和计算设备铺平了道路。

英文摘要:

Increasing the complexity of quantum photonic devices is essential for many optical information processing applications to reach a regime beyond what can be classically simulated, and integrated photonics has emerged as a leading platform for achieving this. Here, we demonstrate three-photon quantum operation of an integrated device containing three coupled interferometers, eight spatial modes and many classical and nonclassical interferences. This represents a critical advance over previous complexities and the first on-chip nonclassical interference with more than two photonic inputs. We introduce a new scheme to verify quantum behaviour, using classically characterised device elements and hierarchies of photon correlation functions. We accurately predict the device's quantum behaviour and show operation inconsistent with both classical and bi-separable quantum models. Such methods for verifying multiphoton quantum behaviour are vital for achieving increased circuit complexity. Our experiment paves the way for the next generation of integrated photonic quantum simulation and computing devices.
