Abstract
A superconducting logic circuit is configured by using two kinds of input-output type quantum flux parametrons (QFP), that is, a periodically excited input-output type QFP and an arbitrarily excited input-output type QFP. The periodically excited QFP is excited by periodically varying exciting magnetic flux to amplify a binary magnetic flux. The arbitrarily excited QFP is excited by magnetic flux output signals of upstream QFPs.
