论文摘要
我们使用扫描超导量子干扰装置（Squid）来成像由设计用于量子计算的超导装置产生的磁通量。纳米尺度的鱿鱼尖端探针揭示了通过电路的超导电流的流以及被困磁通量的位置。特别是，从量子线附近流出的电流线的图显示了这些元素的耦合方式，从而提供了有关如何优化量子控制的见解。
We use a scanning superconducting quantum interference device (SQUID) to image the magnetic flux produced by a superconducting device designed for quantum computing. The nanometer-scale SQUID-on-tip probe reveals the flow of superconducting current through the circuit as well as the locations of trapped magnetic flux. In particular, maps of current flowing out of a flux-control line in the vicinity of a qubit show how these elements are coupled, providing insight on how to optimize qubit control.
