Abstract: This invention enables high temperature superconducting (HTS) metal oxide materials ReBa2Cu3Ox ((RE)BCO) to carry high superconducting currents at high current densities under high magnetic field (?3 Tesla), in all orientations of the field, and at high temperatures (65 Kelvin). The superconductor is adapted to carry current in a superconducting state, with the superconductor having a current (I) carrying capacity of at least 250 A/cm width, in a field of 3 Tesla (T), at 65 Kelvin (K), at all angles relative to the coated conductor. More preferably, the current carrying capacity extends through the range of substantially 250 A/cm to 500 A/cm. Excellent performance is achieved by use of intrinsic pinning centers in the HTS compound. The invention preferably does not require the addition of extra elements or compounds or particles to the superconducting compound during synthesis, nor does it require extra process steps.

Abstract: SQUIDs may detect local magnetic fields. SQUIDS of varying sizes, and hence sensitivities may detect different magnitudes of magnetic fields. SQUIDs may be oriented to detect magnetic fields in a variety of orientations, for example along an orthogonal reference frame of a chip or wafer. The SQUIDS may be formed or carried on the same chip or wafer as a superconducting processor (e.g., a superconducting quantum processor). Measurement of magnetic fields may permit compensation, for example allowing tuning of a compensation field via a compensation coil and/or a heater to warm select portions of a system. A SQIF may be implemented as a SQUID employing an unconventional grating structure. Successful fabrication of an operable SQIF may be facilitated by incorporating multiple Josephson junctions in series in each arm of the unconventional grating structure.
