Abstract
A driver circuit for a qubit comprises a first Josephson junction or first array of Josephson junctions, having a first critical current, and a second Josephson junction or second array of Josephson junctions, having a second critical current. An inductive path connects a first side of the first junction to a first side of the second junction, and ground connections connect respective second sides of the first junction and the second junction to a fixed reference potential. The data input and pulse output are at an intermediate point of said inductive path. The driver circuit comprises a differential clock input comprising two connections through respective inductors, one to said first half of said first junction and the other to said first half of said second junction. Said first and second critical currents differ from each other by a predefined offset.
