Experiments based on the single electron transport effect, the quantum Hall effect, and this phenomenon form the so-called quantum metrology triangle.
In 2012, experimenters first demonstrated a magnetic analogue of this phenomenon that is known as coherent quantum phase slip. Experiments based on the single electron transport effect, the quantum Hall effect, and this phenomenon form the so-called quantum metrology triangle. In combination with the quantum Hall effect, this phenomenon allows precise determination of Planck's constant h and the elementary charge e, as this phenomenon's namesake constant equals (*) 2e/h. Two devices operating via this phenomenon are placed on the arms of a loop and experience a biasing current that reverses direction at each increment of half the magnetic flux quantum, producing sensitive magnetometers. For 10 points, name this phenomenon in which Cooper pairs tunnel through a thin insulator between two superconductors, used in making SQUIDs ["squids"].
