Abstract
Magnetic flux in mesoscopic rings in the quantum Smoluchowski regime is investigated. Quantum corrections to the dissipative current are shown to form multistable steady states and can result in statistical enhancement of the magnetic flux. The relevance of quantum correction effects is supported via the entropic criterion. A possible application for a qutrit architecture of quantum information is proposed.
