Abstract: Apparatus and methods enable active compensation for unwanted discrepancies in the superconducting elements of a quantum processor. A qubit may include a primary compound Josephson junction (CJJ) structure, which may include at least a first secondary CJJ structure to enable compensation for Josephson junction asymmetry in the primary CJJ structure. A qubit may include a series LC-circuit coupled in parallel with a first CJJ structure to provide a tunable capacitance. A qubit control system may include means for tuning inductance of a qubit loop, for instance a tunable coupler inductively coupled to the qubit loop and controlled by a programming interface, or a CJJ structure coupled in series with the qubit loop and controlled by a programming interface.

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.
Abstract translation: SQUID可以检测局部磁场。 具有不同尺寸的SQUIDS，因此灵敏度可以检测不同的磁场强度。 SQUID可以被定向以检测各种取向中的磁场，例如沿着芯片或晶片的正交参考系。 SQUIDS可以与超导处理器（例如超导量子处理器）形成或携带在相同的芯片或晶片上。 磁场的测量可以允许补偿，例如允许通过补偿线圈和/或加热器对补偿场进行调谐以温暖系统的选择部分。 SQIF可以被实现为采用非常规光栅结构的SQUID。 可以通过将多个约瑟夫逊结串联在非常规光栅结构的每个臂中来促进可操作的SQIF的成功制造。
