Abstract
A logic circuit arrangement includes signal input and signal output devices and a number of SFQ circuits having Josephson junctions in which carrier devices are used for carrying digital information. The SFQ circuits are sampled at the input/output for producing DC voltages and a train having at least two single flux quanta is used as a carrier device for information and phase locking between at least two Josephson junctions is used to provide at least two different dynamic states of which at least one provides an output signal.
