论文摘要
我们开发了一种新型的磁力计，该磁力计由设置在双稳定状态的混合量子干扰装置（Hyquid）组成。我们在闩锁模式下演示了其操作，该操作可用于测量应用通量中的小变化。该设备可用于使用直接电阻测量值来探测超导电路的通量状态，从而使其适合于具有低背部功能的简单量子读数。
We have developed a new type of magnetometer consisting of a Hybrid Quantum Interference Device (HyQUID) that is set in a bi-stable state. We demonstrate its operation in a latching mode that can be employed to measure small changes in the applied flux. The device can be used to probe the flux state of a superconducting circuit using straightforward electrical resistance measurements, making it suitable as a simple qubit readout with low back-action.
