ABSTRACT:
According to the present invention, there is provided a superconducting circuit including a Josephson tunnel junction 1 and a load resistor 2 connected in parallel to the Josephson tunnel junction, in which a current source 5 is connected to the input terminal for the Josephson tunnel junction 1 and which has a pulse generator 3 in order to superimpose a pulse current to the current i from the current source 5.
As the input signal, a current pulse is given to the current i within the range of below the critical current of the Josephson tunnel junction by means of the foregoing pulse generator 3 so that an excellent separation of the input and output is achieved without using any magnetic coupling circuit.
