The authors neglected to cite previous studies related to the use of current injection as a viable means to control SQUIDs. These additional references are listed below as references 1, 2 and 3 and should appear in the Introduction section as below.
“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”.
should read:
“Current injection has been demonstrated before as a viable means to control SQUIDs1,2,3,12–14 dominated either by geometric or kinetic inductances. Several of these implementations used a large pickup loop to convert an applied magnetic field into a current bias which was injected into a smaller, more sensitive readout SQUID”.
In addition, the authors would like to alert readers to a similar result published prior to final acceptance of this paper. This is listed below as reference 4.
