论文摘要
我们提出了一种基于纤维综合腔中捕获光子的量子记忆协议,该腔体由带有二分法反射端片的双重纤维组成。通过辅助控制脉冲驱动的腔内bragg散射频率翻译将光子与纤维腔变成共振。存储延迟后,再次通过腔内频率翻译将光子切换为与腔的共振。我们展示了量子级别的带宽相干状态的储存寿命,最多可达16个空腔圆旅行,或200NS,最高总体效率为73%。
We propose a quantum memory protocol based on trapping photons in a fiber-integrated cavity, comprised of a birefringent fiber with dichroic reflective end facets. Photons are switched into resonance with the fiber cavity by intracavity Bragg-scattering frequency translation, driven by ancillary control pulses. After the storage delay, photons are switched out of resonance with the cavity, again by intracavity frequency translation. We demonstrate storage of quantum-level THz-bandwidth coherent states for a lifetime up to 16 cavity round trips, or 200ns, and a maximum overall efficiency of 73%.
