Optical microscope image of a quartz pipette before pulling it into a SQUID-on-tip, or multi-SQUID-on-tip. The latter allows in-situ control over the SQUID's response to magnetic field.

Optical microscope image of an asymmetric quartz pipette before pulling it into a SQUID-on-tip with asymmetric junctions.
SQUID-on-tip holders. Right: the usual two-terminal SQUID. Left: an advanced four-terminal SQUID with increased tunability.

SQUID-on-tip mechanical and electrical holders.
