Kind: research · Impact: low

## In brief

- Researchers report photon-pair generation in topological waveguide arrays.
- The approach is described as more robust to fabrication disorder than conventional designs.
- The authors position the work as a route to scalable, identical on-chip quantum light sources.

## Why it matters

Fabrication variability is a major obstacle to producing many identical on-chip photon-pair sources, so a design that tolerates disorder could matter for scaling quantum photonic hardware.
