FLUXOID TRANSMISSION LINE USING SERIES JOSEPHSON JUNCTIONS.

The discrete Josephson junction transmission line which has N series Josephson junctions in each loop is discussed by computer simulation. It is found that a single quantum in this line can be stuffed in about one loop even if the inductance of each loop decreases to be negligibly small, i. e. , the contribution of flux to a fluoxid is descreased. In this line the very small size fluxoid quanta with little flux can be employed as information bits. The resistive Josephson transmission lines whose loops have resistances in series are also discussed. In the resistive lines various operations are possible because of relaxation of the quantization conditions.
