Superconducting quantum interference devices: Grasp of SQUIDs dynamics facilitates eavesdropping

A superconducting quantum interference device is a highly sensitive magnetometer used to measure extremely subtle magnetic fields. It is made of two thin regions of insulating material that separate two superconductors placed in parallel into a ring of superconducting material. Scientists have focused on finding an analytical approximation to the theoretical equations that govern the dynamics of an array of SQUIDs.
