Abstract
A Josephson junction transmission line ( ) for transmitting single flux quantum pulses. The transmission line ( ) includes a current source ( ), a plurality of isolation inductors ( ) electrically coupled in series along the transmission line ( ), and a plurality of Josephson junction circuits ( ) electrically coupled in parallel along the transmission line ( ). Each of the Josephson junction circuits ( ) includes only a Josephson junction ( ) and a parasitic inductor ( ) coupled in series. The Josephson junction circuits ( ) do not include a damping resistor in order to reduce timing uncertainty and to enhance propagation speed.
