Working devices

In the end, the team used this method to make three different quantum electronic devices that worked.A superconducting switch, also known as a Josephson junction, is one of these devices.The building blocks of superconducting quantum computers’ quantum bits, or qubits, are Josephson junctions.

They can also be used in a lot of other ways, like in devices that can measure magnetic fields with great precision.

In addition, the team developed two related devices:a very sensitive device for controlling the movement of electricity, literally one electron at a time, as well as a spectroscopic tunneling device and a single-electron transistorThe first is crucial to understanding superconductivity, whereas the second has numerous uses due, in part, to its extreme sensitivity to electric fields.
