A SQUID is a superconducting quantum interference device.
Its loop contains one or two tiny non-superconducting interruptions called Josephson junctions. External magnetic field changes the currentβvoltage behavior across those junctions in a predictable way.
That is the signal path: magnetic flux influences a superconducting circuit, and the circuit produces a readable electrical response.
Typical SQUID systems require cryogenic temperatures. Sensitivity comes with operating constraints.
The colder the platform, the more carefully the whole measurement system must be engineered.
