Circuit with Josephson contacts for the non-destructive reading out of fluxon states

摘要

The invention relates to an arrangement for the non-destructive reading out of individual fluxons, which are stored in a shift register by a high number of concentrated Josephson contacts and inductances. The arrangement is an interferometer with two Josephson contacts, which is coupled extremely strongly to the corresponding storage loop of the shift register. For the case of negligible stray fluxes, dimensioning specifications are prescribed for the Josephson contacts of the reading and storage loop.
