US quantum simulator mimics real-world temperatures with two independent controls

A Rice University-led team built a trapped-ion quantum simulator with two independent temperature knobs for heating and cooling.

The setup lets researchers tune temperature and dissipation rate separately, making the thermal environment more realistic.

Using it, the team studied molecular electron transfer and found temperature-dependent efficiency changes plus new behaviors absent at the ground state.

The advance expands what quantum simulators can model, improving studies of temperature-sensitive processes in molecules and materials.
