  Superconducting QUantum Interference Devices (SQUIDs) are extremely sensitive
magnetic flux sensors which render them useful in a wide array of
instrumentation. SQUIDs are often paired with other detectors as a readout
mechanism to obtain quantitative insight. SQUIDs have impacted many fields but
much less addressed is its impact on the field of fundamental physics,
particularly in the search for dark matter. Dark matter is believed to make up
around 27% of all mass-energy content of the universe and will provide critical
insight into understanding large-scale structures of the universe. Axions and
WIMPs are the prominent two dark matter candidates whose search has been fueled
by the usage of SQUID read-outs.
