摘要 针对fJ(飞焦)至单光子极弱能量测量及溯源需求,提出一种纠缠单光子源。通过基于冷原子团的自发四波混频效应产生波长795nm的宣布式纠缠光子对,采用背景辐射抑制与实时补偿、高精度激光稳频、时序脉冲精密同步获得窄线宽、高质量的单光子源。在此基础上,研究了纠缠光子源参数校准方法,进一步建立以量子基准为基础的全新光辐射量值溯源体系,减小了极弱光辐射参数的测量不确定度。

Abstract:A kind of entangled single-photon source was proposed to meet the requirements of the measurement and traceability of very weak energy level from a single-photon to femto-joule. The heralded entangled photon pairs at 795 nm wavelength were generated through four wave mixing based on the cold atoms. The narrowband paired and high-quality single-photon source was obtained through the suppression of background radiance and real-time compensation, high precision laser frequency stabilization, timing pulse precise synchronization. On this basis, the calibration methods of entangled photon source parameter were studied. The further establishment of the new optical radiation traceability system based on the quantum basic standards were considered, which is to reduce the measurement uncertainty of very weak optical radiation parameters.
