- Abstract summary: We demonstrate a fiber-integrated quantum memory entangled with a photon at telecommunication wavelength.
The storage device is based on a fiber-pigtailed laser written waveguide in a rare-earth doped solid and allows an all-fiber stable adressing of the memory.
Our results feature orders of magnitude advances in terms of storage time and efficiency for integrated storage of light-matter entanglement, and constitute a significant step forward towards quantum networks using integrated devices.

- Abstract: The deployment of a fully-fledged quantum internet poses the challenge of
finding adequate building-blocks for entanglement distribution between remote
quantum nodes. An ideal system would combine propagation in optical fibres with
quantum memories for light, leveraging on the existing communication network
while featuring the scalability required to extend to network sizes. Here we
demonstrate a fiber-integrated quantum memory entangled with a photon at
telecommunication wavelength. The storage device is based on a fiber-pigtailed
laser written waveguide in a rare-earth doped solid and allows an all-fiber
stable adressing of the memory. The analysis of the entanglement is performed
using fibre-based interferometers. Our results feature orders of magnitude
advances in terms of storage time and efficiency for integrated storage of
light-matter entanglement, and constitute a significant step forward towards
quantum networks using integrated devices.
