Kind: research · Impact: low

## In brief

- Atomic defects in quantum materials can alter how the material responds to light.
- These changes produce a distinctive optical fingerprint that scientists can measure.
- Detecting such defects is described as difficult, and the optical signature offers a way to spot them.

## Why it matters

Atomic-scale defects matter for future quantum technologies, and a measurable optical signature could give researchers a practical way to detect them.
