TL;DRAbstract

The behavior of a single-contact superconducting interferometer at low temperatures, when its energy of zero point quantum vibrations ℏ(LC)−1/2 is comparable to the thermal energy kT, is studied. Hysteresis-free and hysteretic regimes of operation of the interferometer are examined. It is shown that taking into account quantum corrections leads to effects which, probably, can be observed experimentally.
