Kind: research · Impact: medium

## In brief

- Researchers report high-rate entanglement swapping between two remote entanglement sources connected over deployed fibres in New York City.
- The work is described as scalable and was performed on existing commercial fibre infrastructure rather than a dedicated laboratory link.
- The results are published in a peer-reviewed APS journal article with a DOI, 10.1103/4xr6-2w3d.

## Why it matters

It shows that entanglement swapping, a building block for quantum networks, can run at useful rates over fibre already deployed in an urban environment, which bears on how quantum repeaters and networks might be built.
