  We present a holographic model of the SQUID (Superconducting QUantum
Interference Device) in the external magnetic field. The model of the
gravitational theory considered in this paper is the Einstein-Maxwell-complex
scalar model on the four-dimensional Anti-de Sitter Schwarzschild black brane
geometry, where one space direction is compacted into a circle and we arrange
the coefficient of the time components profile so that we can model the SQUID,
where the profile plays the role of the chemical potential for the cooper pair.
