Superconducting Quantum Interference Devices (SQUIDs) are highly sensitive magnetometers that exploit the quantum mechanical properties of superconductors to measure extremely weak magnetic fields. They work based on the principles of quantum interference and can detect magnetic fields as small as a few femtoteslas, making them invaluable in various applications that require high precision.
congrats on reading the definition of Superconducting Quantum Interference Devices (SQUIDs). now let's actually learn it.
