What is SQUID sensor?

A SQUID (superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops containing Josephson junctions.

How does a SQUID sensor work?

Every SQUID consists of a macroscopic superconducting loop with one or two weak links (Josephson Junctions). When cooled below the critical temperature the magnetic flux will be trapped in the loop. The super current (isupra) causes the magnetic flux to be a multiple of the fluxoid Φ0.

What does a SQUID magnetometer measure?

A SQUID magnetometer is used to measure extremely subtle magnetic field based on superconducting loops containing Josephson junctions.

What is a SQUID in quantum computing?

The Impact. Superconducting devices are candidates for developing qubits. One type of device is called a SQUID for superconducting quantum interference device. It is based on a superconducting loop containing one or two Josephson junctions and allows measurement of quantized magnetic energy.
