Optical experiment demonstrates the strong Mpemba effect in a single qubit

The 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.

Who’s affected

  • physicists working on quantum thermodynamics and non-equilibrium dynamics

Typically, after a physical system is disturbed, it can gradually return toward a state of thermal equilibrium by exchanging heat with its surroundings. Thermal equilibrium is a state in which there is no net transfer of heat between the system and its surroundings.
