Abstract

Efficient and low-noise distribution of photons is essential for quantum technology networks. Current strategies focus on low-loss distribution channels or the use of quantum repeaters. I will present a surprising alternate strategy: transporting photons stored in a quantum hard drive. Recent results demonstrate the potential for such a device in rare-earth ion crystals with coherence lifetimes greater than 6 hours. With a sufficiently high photonic storage capacity, quantum hard drives will enable new regimes of science, such as optical astronomy below 1 µas resolution using very long baseline interferometry.
