ABSTRACT
Macroscopic quantum interference acquires new features in the two-junction interferometer—the system where two Josephson junctions connect two parts of a superconducting loop (Figure 1).† The most important of these features is the possibility of a nonvanishing mean voltage ()https://www.w3.org/1998/Math/MathML">V¯1=V¯2=V¯https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315141572/0ba78ca1-05bc-4a29-bdf3-856e8fbc4b17/content/eq620.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> (a) Two-junction superconducting quantum interferometer and (b, c) its equivalent circuits. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315141572/0ba78ca1-05bc-4a29-bdf3-856e8fbc4b17/content/fig7_1.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
