Some of the behaviour of a quantron(one-junction interferometer)with a Josephson gate is simulated.This quantron was proposed by Likharev in 1977 and is called the Parametric Quantron.By proper control of its critical current with time, alternative stable states of the equantron can be selected by a switching signal whose product of the energy dissipation E_c and the switching time τ is as low as 10^2h(where h is Planck's constant). In this experiment, a simulator based on the analyogy between a Josephson junction and a phase-locked loop is used.Analog systems are flexible and easier to assemble than the mechanical analog.
