摘要：
Loss of photons over long-distance connections limits the development of quantum networks, necessitating the use of quantum 'repeater' systems to boost signals between network nodes. Erbium ions incorporated into calcium tungstate crystals have been found to emit photons in the telecommunications frequency band that are indistinguishable from each other, and thus show promise for use in such repeaters.
