FIG. 11 shows a circuit diagram implementing the single-read RQL D-register 600 of FIG. 6 as an example RQL-compatible superconducting circuit 1100, similar in form and function to circuit 700 of FIG. 7, but reducing, from two to one, the number of DC flux bias transformers in the circuit by implementing a Y-Δ transform of the central inductance network in the body stage 702 to arrive at body stage 1102, having inductors LL1 and LL2. Tail stage 1104 is unchanged from tail 704. Circuit 1200 of FIG. 12 provides a similar variation of the dual-read RQL D-register 800 of FIG. 8 as compared to circuit 900 of FIG. 9, illustrating that the variation of the latch-based NDRO circuit shown in FIG. 11 can be built to a dual-read or multiple-read configuration by adding on NDRO tail stages 1204, 1206 to nodes 1208, 1210. Tail stages 1204, 1206 are unchanged from tail stages 904, 906; only the topology of body stage 1202 differs from the topology of body stage 902.
