  • Patent number: 9335385
    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.

  • Patent number: 8405468
    Abstract: An electronic filtering device includes continuous trace on a dielectric substrate and a dissipation layer communicatively coupled to the trace. The dissipation layer may include disconnected metal particles, which may be embedded in a substrate, for example in an epoxy. The continuous trace may be meandering, for example crenulated, coil or spiral signal path. At least a second continuous trace may be spaced from the first by the substrate, and conductively coupled by a via. The electronic filtering device may be used in one or more printed circuit boards (PCBs) that form stages of an input/output system.

  • Patent number: 8355765
    Abstract: Magnetic shields and magnetic shielding systems are described. The excessive spatial demands of known mu-metal/cryoperm and superconducting shielding systems are reduced by a new multi-piece shield construction approach. A complete magnetic shielding system for use with superconducting-based computing systems, such as superconducting quantum computing systems, is also described. This complete system may include mu-metal/cryoperm shields and superconducting shields using either compensatory magnetic fields, expulsion by temperature gradients, or a combination of the two.

  • Patent number: 8228688
    Abstract: A device is at least partially contained within a shielded enclosure formed by a first material that has a high thermal conductivity and plated with a second material that is superconductive below a critical temperature. An exterior of the shielded enclosure is at least partially wound by a compensation coil that is coupled to a current source. One or more measurement devices are responsive to magnetic fields in close proximity to the device, allowing compensation by controlling current to the compensation coil. Thus, magnetic shielding may be provided by compensation fields that may be trapped within the shielded enclosure when the system is cooled below the critical temperature of the second material. Radiation shielding may be provided by cooling the shielded enclosure to a temperature that is approximately equal to the temperature of the device.
