Thermally isolated ground conductor discontinuities for qubit circuits

A quantum mechanics circuit (100) includes: a first electrical conductor (104) and a second electrical conductor (106) disposed on a substrate (102) and spaced apart to provide a gap (112) therebetween; and a third electrical conductor (108) electrically connecting the first electrical conductor and the second electrical conductor. The third electrical conductor has a thermal conductivity substantially lower than the thermal conductivity of the first and second electrical conductors to provide thermal isolation. Quantum bits (206) of a superconducting quantum processor (204) are provided on a substrate and electrically connected to ground via at least one of the first or second electrical conductors. 一种量子力学电路(100)，包括：第一电导体(104)和第二电导体(106)，其设置在衬底(102)上并且间隔开以在其间提供间隙(112)；以及第三电导体(108)，其电连接第一电导体和第二电导体。第三电导体具有实质上低于第一电导体和第二电导体的热导率的热导率，以提供热隔离。超导量子处理器(204)的量子位(206)被提供在衬底上并且经由第一或第二电导体中的至少一个而被电气地连接到地。
