What Does SQUID Stand For?

SQUID stands for Superconducting Quantum Interference Device

SQUID, or Superconducting Quantum Interference Device, is a highly sensitive magnetometer used to measure extremely weak magnetic fields. It leverages the principles of superconductivity and quantum interference to achieve remarkable sensitivity, allowing for applications in various fields such as neurology, geology, and materials science. SQUIDs can detect magnetic signals at the femtotesla level, making them essential tools in both research and industrial applications for non-invasive measurements.
