Applications of the Main Devices Based on Josephson Junction: A Review

In this paper we present a review of the main applications of Josephson Junction (JJ). This device bases its properties on the Josephson Effect, based on the relationship between Tunnel Effect and Superconducting Theory. The properties of JJ allow to realize Superconducting Quantum Interference Devices (SQUIDs), used in medical field, or industrial level electronic circuits such as Superconducting Qubits. We also describe the hybrid technology named RSFQ-CMOS, which is not realized yet for general purposes because it requires cryogenic cooling system. Although, if this problem will be bypassed, the devices based on Josephson Junction will be ready to substitute the current electronic and its limitations.
