Abstract

We present the results of experimental study of nondegenerate spontaneous parametric downconversion in a single-resonance optical parametric oscillator with two PPKTP crystals. The possibility of generating narrow-band polarization-entangled photons, one of which has a wavelength of 580 nm and a spectral width of 8.0 ± 1.5 MHz, has been shown. This makes such a source of photon pairs compatible with solid-state quantum memory based on a Y₂SiO₅ : Eu³⁺ crystal, which is promising for quantum repeaters.

基于固态量子存储的量子中继器窄带纠缠光子对源

本文给出了双PPKTP晶体单共振光学参量振荡器非简并自发参量下转换的实验研究结果。实验证明了产生窄带偏振纠缠光子的可能性，其中一个光子的波长为580 nm，光谱宽度为8.0±1.5 MHz。这使得这种光子对源与基于Y2SiO5: Eu3+晶体的固态量子存储器兼容，这对于量子中继器很有希望。
