Magnetic flux noise in the three Josephson junctions superconducting ring
We analyze the influence of noise on magnetic properties of a superconducting loop which contains three
 Josephson junctions. This circuit is a classical analog of a persistent current (flux) qubit. A loop supercurrent
 induced by external magnetic field at the presence of thermal fl...

| description | We analyze the influence of noise on magnetic properties of a superconducting loop which contains three
Josephson junctions. This circuit is a classical analog of a persistent current (flux) qubit. A loop supercurrent
induced by external magnetic field at the presence of thermal fluctuations is calculated. In order to
get connection with experiment we calculate the impedance of the low-frequency tank circuit which is inductively
coupled with a loop of interest. We compare obtained results with the results in quantum mode —
when the three junction loop exhibits quantum tunneling of the magnetic flux. We demonstrate that the
tank-loop impedance in the classical and quantum modes have different temperature dependence and can be
easily distinguished experimentally.
