Magnetic field in the loop changes the phase of the quantum wave function and changes the current through the ring
mK SQUID design for XEUS X03 TRP
(a) Schematics of the damping circuit for the un SQUID.
(b) Chip carrier with the SQUID chip and SMD components.
(c) The time trace of the SQUID current taken in the negative-resistance region indicates stable operation without parasitic oscillation.
Potentially lower noise, improved impedance matching
