TL;DR: The cryotron as mentioned in this paper is a device based on the destruction of superconductivity by a magnetic field, which can be used for computer applications, such as superconducting sensors.
Abstract: The study of nonlinearities in nature suitable for computer use has led to the cryotron, a device based on the destruction of superconductivity by a magnetic field. The cryotron, in its simplest form, consists of a straight piece of wire about one inch long with a single-layer control winding wound over it. Current in the control winding creates a magnetic field which causes the central wire to change from its superconducting state to its normal state. The device has current gain, that is, a small current can control a larger current; it has power gain so that cryotrons can be interconnected in logical networks as active elements. The device is also small, light, easily fabricated, and dissipates very little power.

TL;DR: A 3-terminal, nanowire-based superconducting electrothermal device which has no Josephson junctions, which has immediate applications in classical and quantum communications, photon sensing, and astronomy, and its input characteristics are suitable for integration with existingsuperconducting technologies.
Abstract: Superconducting electronics based on Josephson junctions are used to sense and process electronic signals with minimal loss; however, they are ultrasensitive to magnetic fields, limited in their amplification capabilities, and difficult to manufacture. We have developed a 3-terminal, nanowire-based superconducting electrothermal device which has no Josephson junctions. This device, which we call the nanocryotron, can be patterned from a single thin film of superconducting material with conventional electron-beam lithography. The nanocryotron has a demonstrated gain of >20, can drive impedances of 100 kΩ, and operates in typical ambient magnetic fields. We have additionally applied it both as a digital logic element in a half-adder circuit, and as a digital amplifier for superconducting nanowire single-photon detectors pulses. The nanocryotron has immediate applications in classical and quantum communications, photon sensing, and astronomy, and its input characteristics are suitable for integration with ex...

TL;DR: The cryotron, a new computer component based on the phenomenon of superconductivity, may have an important influence on future developments in the field of computers and data-handling machines.
Abstract: The cryotron, a new computer component based on the phenomenon of superconductivity, may have an important influence on future developments in the field of computers and data-handling machines. At the present time the cryotron has a slower switching speed than transistors, but there are reasons for believing that the speed can be increased considerably.

TL;DR: In this paper, the dependence of IJ, the maximum zerovoltage current, on magnetic fields for a series of Josephson junctions of differing size when compared with λJ is discussed.
Abstract: This paper discusses the dependence of IJ, the maximum zero‐voltage current, on magnetic fields for a series of Josephson junctions of differing size when compared with λJ, the Josephson penetration depth. The experimental results are in excellent agreement with the calculations; in particular, for junctions with L≫λJ, the Meissner effect and overlapping vortex structure are clearly demonstrated. The current density distributions are also shown. Finally, the implications of size dependence for tunneling cryotron devices is discussed.

TL;DR: A basic associative memory utilizing cryogenic circuitry is described and its functions are compared with those of previously published Associative memory descriptions.
Abstract: A basic associative memory utilizing cryogenic circuitry is described and its functions are compared with those of previously published associative memory descriptions. The ordered-retrieval sorting algorithm is described, along with its implementation by means of a ternary interrogating counter. A sorting example is given. The sorting efficiency is discussed and an efficiency formula is given. The required additions to the basic memory are outlined. Finally, some of the basic cryotron circuits are illustrated and their operation described.
