> In 1956, MIT electrical engineer Dudley Buck published a description of a superconducting computer switch called the cryotron. The device was little more than two superconducting wires: One was straight, and the other was coiled around it. The cryotron acts as a switch, because when current flows through the coiled wire, its magnetic field reduces the current flowing through the straight wire. > [Karl Berggren] dubbed his superconducting nanowire device the nano-cryotron in tribute to Buck... The nano-cryotron uses heat to trigger a switch, rather than a magnetic field. Dudley Buck's cryotron: https://en.wikipedia.org/wiki/Cryotron https://en.wikipedia.org/wiki/Cryotron
