论文摘要
集成光子学的进展可以使单个基材上的几个基本功能结合实现高级结构化芯片。我们报告了在氯酸锂上的整体整合量子光子实现，在该实现中，已同时利用非线性光学和电磁性能，用于生成可构型的可配置的两光子状态。利用皮秒泵激光器和电信组件，我们证明了各种路径编码的两光子状态的产生，显示了Hong-ou-mandel干扰的94 \％原始可见性。如此高度集成的光子纠缠源的多功能性和性能使探索更复杂的量子信息处理协议可以在通信，计量和处理任务中找到应用。
Progress in integrated photonics enables combining several elementary functions on single substrates for realizing advanced functionnalized chips. We report a monolithic integrated quantum photonic realization on lithium niobate, where nonlinear optics and electro-optics properties have been harnessed simultaneously for generating heralded configurable, two-photon states. Taking advantage of a picosecond pump laser and telecom components, we demonstrate the production of various path-coded heralded two-photon states, showing 94\% raw visibility for Hong-Ou-Mandel interference. The versatility and performance of such a highly integrated photonic entanglement source enable exploring more complex quantum information processing protocols finding application in communication, metrology and processing tasks.
