 The Josephson diode effect is a phenomenon observed in three terminal Josephson devices consisting of an INAS quantum world two-dimensional electron gas, 2DG, proximitized by an epitaxial aluminum superconducting layer. This effect allows for the manipulation of the current phase relationship between two signals, enabling the simultaneous rectification of two signals and non-linear intermodulation effects. Additionally, this effect can be controlled by applying a magnetic field or electrostatically gating the device. This makes it possible to use these devices as gate-gainable building blocks in designing topologically protected qubits. This article was authored by Mohit Gupta, Gino V.
