Schematic of the SQUID array. (a) The phase drop across a single SQUID junction is proportional to the node flux Φ n (indicated by the circle) at the end of the transmission line. (b) If we replace the single junction by an serial array of M junctions with M times larger Josephson energy, the phase drop across each junction is by a factor of M smaller while the total effective Josephson inductance stays the same.
