Direct current Superconducting QUantum Interference Device (dc SQUID) is the most sensitive magnetic flux and field detector known so far [1,2]. Due to the low operating temperature and quantum working principle, a SQUID exhibits an equivalent energy sensitivity that approaches the quantum limit. Thanks to their unique properties, SQUID devices are widely used in several applications [3,4] like biomagnetism, magnetic microscopy, nondestructive evaluation, geophysics, astrophysics, quantum information, particle physics, and, recently, also in nanoscience.
