Josephson junction (plural Josephson junctions)
(physics) a weak insulating barrier between two superconductors, used as an ultrafast switch
Microsoft has variously estimated that one topological Majorana qubit is worth between 10 and 1,000 Josephson junction qubits in terms of error-corrected logical qubits. Source: Internet
It is based on the AC Josephson effect and uses only one Josephson junction. Source: Internet
RF SQUIDs can work with only one Josephson junction ( superconducting tunnel junction ), which might make them cheaper to produce, but are less sensitive. Source: Internet
