Scalability and miniaturization are hallmarks of solid-state platforms for photonic quantum technologies. Still a main challenge is two-photon interference from distinct emitters on chip. This requires local tuning, integration, and novel approaches to understand and tame noise processes. A promising platform is that of molecular single-photon sources. Thousands of molecules with optically tunable emission frequency can be easily isolated in solid matrices and triggered with pulsed excitation. We here discuss Hong–Ou–Mandel interference experiments using several couples of molecules within few tens of microns. Quantum interference is observed in real time, enabling the analysis of local environment effects at different time scales.

来自同一芯片上不同分子的实时双光子干涉

可扩展性和小型化是光子量子技术固态平台的标志。仍然一个主要挑战是来自芯片上不同发射器的双光子干涉。这需要局部调整、集成和新颖的方法来理解和驯服噪声过程。一个有前途的平台是分子单光子源。数千个具有光学可调发射频率的分子可以很容易地在固体基质中分离出来,并通过脉冲激发来触发。我们在这里讨论使用几十微米内的几对分子的 Hong-Ou-Mandel 干涉实验。实时观察量子干涉,可以分析不同时间尺度的局部环境影响。
