In this paper the flux transfer device is reviewed. Generalized magnetic flux, defined as the time integral of voltage, is used to describe the device characteristics. The Josephson junction and inductor are the main circuit elements in flux transfer devices, because they maintain the value of the time integral of voltage constant. Flux transfer devices are based on either an rf SQUID or a fluxon device. Four devices, including the parametric quantron and the quantum flux parametron, are reviewed as applications of the RF SQUID. The fluxon feedback oscillator and the soliton device are also reviewed as applications of the fluxon device. Next, the quantum flux parametron is described. The parametron principle and the fundamental properties of the quantum flux parametron, such as gain, switching speed, and power dissipation, are discussed. Logic circuits and a memory cell are also reviewed. A new analog-to-digital converter is proposed as an application of the quantum flux parametron.
