Abstract

A mathematical model of quantum processes in an asymmetric interferometer of ultra-small inductance L0 ≈ 10–13 H, shunted by a superconducting highly inductive circuit L1 >> L0·107, is constructed. The model was verified by comparing the calculated model parameters with the experimentally measured values.

Key words: asymmetric quantum interferometer, Josephson point contact, current and magnetic field discretization.
