Quantum networks built on distribution of entangled photons (2022 Physics Nobel Prize) enable fully-secure data transmission over optical fiber and satellite communications. To overcome propagation loss and extend the range of entanglement distribution, quantum repeaters are needed to teleport entanglement between multiple entangled pairs. This “quantum repeater” protocol requires that all entanglement sources involved to fire simultaneously.
However, commercially available entangled photon sources are probabilistic—working only 1% of the time—making it extremely difficult, if not impossible, to precisely control the firing of needed entangled photon sources, limiting their use in building large-scale quantum networks (no more than 10s of kilometers).
