A double potential energy well with quantum wave functions on a ladder of different energy levels N. E. Frattini et al.
A 135-year-old chemistry law is getting a quantum makeover. An experiment with a single quantum bit, or a qubit, has uncovered that the Arrhenius equation, which describes how reaction rates relate to temperature, must be modified to apply in the quantum realm.
Rodrigo Cortiñas at Yale University says he never doubted that the Arrhenius equation would translate directly to a quantum experiment – until he and…
