We report the results of a stability analysis of coherent oscillations in series arrays of Josephson junctions with a matched resistive load. We find that arbitrarily large, dc biased arrays of Josephson junctions will phase lock most strongly when the capacitance parameter βc ≊1, and the bias current is about twice the critical current of the individual junctions.

    Adiabatic quantum-flux-parametron (AQFP) logic can achieve high energy-efficiency. The bit energy and bit-error-rate (BER) of AQFP gates with under-damped Josephson junctions were simulated. The results indicate that the bit energy reaches 12 yJ, which is only 20% of the thermal energy at 4.2 K,...
