Number of Josephson junctions on a superconducting integrated circuit chip
Photograph of the D-Wave TwoX "Washington" quantum annealing processor chip mounted and wire-bonded in a sample holder. This chip was introduced in 2015 and includes 128,472 Josephson junctions.
The Josephson junction count is the number of Josephson junctions on a superconducting integrated circuit chip. Josephson junctions are active circuit elements in superconducting circuits. The Josephson junction count is a measure of circuit or device complexity, similar to the transistor count used for semiconductor integrated circuits.
Examples of circuits using Josephson junctions include digital circuits based on SFQ logic (e.g., RSFQ, RQL, adiabatic quantum flux parametron), superconducting quantum computing circuits, superconducting analog circuits, etc.
