Corrigendum: nanoSQUID operation using kinetic rather than magnetic induction

“Current injection has been demonstrated before as a viable means to control SQUIDs12–14 dominated by geometric inductance. These directly-coupled SQUIDs used a large pickup loop to convert an applied magnetic field into a current bias which was injected a smaller, more sensitive readout SQUID. Although the readout SQUIDs in these devices were smaller than the pickup loops, they still used large geometric inductors to route the injected current”.
