Advancements in Erbium-Doped Silica Fibers for Quantum Networks: Ultra-Long Population Storage and Ultra-Narrow Homogeneous Linewidths at Millikelvin Temperatures
We demonstrate ultra-long population storage ( ∼ 9 hours) and ultra-narrow homogeneous linewidths ( ∼ 8 kHz) in erbium-doped silica fibers (EDF) at ∼ 7 mK using spectral hole burning and photon-echo techniques. These results establish EDF as a strong candidate for fiber-based quantum networks.
