论文摘要
高速通量纠缠光子源是量子光学研究和应用的关键资源。在这里，它在隔离器（LNOI）芯片上的氯酸锂中实现，具有2.79*10^11 Hz/mW光子对速率和1.53*10^9 Hz/nm/mw光谱亮度。与现有技术相比，这些数据被超过两个数量级增强。 130 nm的宽带宽已设计用于8通道多路复用的能量时纠缠。通过高伸入频率相关性和弗朗森干扰可见度高达99.17％，这种能量时纠缠多路复用进一步提高了高频率数据速率，并保证在芯片上量子信息处理中广泛应用。
High-flux entangled photon source is the key resource for quantum optical study and application. Here it is realized in a lithium niobate on isolator (LNOI) chip, with 2.79*10^11 Hz/mW photon pair rate and 1.53*10^9 Hz/nm/mW spectral brightness. These data are boosted by over two orders of magnitude compared to existing technologies. A 130-nm broad bandwidth is engineered for 8-channel multiplexed energy-time entanglement. Harnessed by high-extinction frequency correlation and Franson interferences up to 99.17% visibility, such energy-time entanglement multiplexing further enhances high-flux data rate, and warrants broad applications in quantum information processing on a chip.
