The states of two phaseﰱcoupled superconducting rings have been investigated. Multiple current states have been revealed in the dependence of the critical current on the magnetic field. The performed calﰱ culations of the critical currents and energy states in a magnetic field have made it possible to interpret the experiment as the measurement of energy states into which the system comes with different probabilities because of the equilibrium and nonequilibrium noises upon the transition from the resistive state to the superﰱ conducting state during the measurement of the critical current.
