Learn MoreThis means that at any non-zero temperature the persistent current state will eventually decay (by tunneling or thermal activation) to a state with no current, and the energy dissipated as heat. However, this requires macroscopic fluctuations (involving the motion of many electrons), and it is therefore extremely unlikely.
