MMC needs stable magnetic field
Persistent field current on chip
• Charging the on-chip persistent current– Applying current to the on-chip field coil
→ maximum 10 G– Using magnetic field from external persistent loop
→ maximum 20 G• Heater operation
– Heater on part of the on-chip persistent loop– Current pulse on SQUID junctions
