Abstract

The authors study the frequency dependent damping in rapid single flux quantum (RSFQ) circuits as means to reduce dissipation and consequent decoherence in RSFQ/qubit circuits. They show by simulations and experiments that stable RSFQ operation can be achieved by shunting the Josephson junctions with an RC circuit instead of a plain resistor. The authors derive criteria for the stability of such an arrangement and discuss the effect on decoherence.
