Kind: research · Impact: low

## In brief

- An optical experiment demonstrated the strong Mpemba effect in a single qubit.
- The Mpemba effect is the counterintuitive case where a system disturbed further from equilibrium relaxes faster toward it.
- The source describes the general process of systems relaxing toward thermal equilibrium by exchanging heat with their surroundings.

## Why it matters

The result extends the strong Mpemba effect, a non-equilibrium relaxation phenomenon, to a single quantum two-level system tested optically, which is relevant to how quantum systems thermalize.
