Abstract
The disclosure relates to a method for providing a logic circuit element. The method includes arranging a series of Josephson junctions between a first Josephson junction and a second Josephson junction, the first Josephson junction having a first critical current (Ic1) and the second Josephson junction having a second critical current (Ic2); providing a working current to the first Josephson junction, the working current transmitting to the second Josephson junction through the series of the Josephson junctions; wherein the working current is sufficiently high to trigger the second Josephson junction while sufficiently low to not disturb super-conductivity of the series of intermediate Josephson junctions.
