Magnetic quantum periodicity in the dc voltage is observed when asymmetric rings are switched between superconducting and normal state by a noise or ac current. This quantum effect is used for the detection of a non-equilibrium noise using a system of 667 asymmetric aluminum rings of 1 μm diameter connected in series. Any noise down to the equilibrium one can be detected with large number of asymmetric rings. The equilibrium noise can induce the dc voltage close to the superconducting transition. In our sample we observe the dc voltage oscillation only below the superconducting transition.
