    • A Josephson signal detector is presented which includes (1) a sensor with at least one Josephson junction (e.g., a SQUID) and (2) a comparator (e.g., an analog-to-digital converter); a measurement system using such detector; and a method of using such detector and measurement system. The detector can be, e.g., a digital SQUID. The detector can also include a readout circuit for reading out the output of the comparator. In one aspect of the invention, the sensor, or both the sensor and readout circuit, are powered by a DC current source. Through use of the DC current source, it is possible to provide, e.g., a digital SQUID, having reduced crosstalk and reduced fluctuation of ground potential, and which is kept from an increase in noise or a miss operation.
    • 提出了约瑟夫逊信号检测器,其包括(1)具有至少一个约瑟夫逊结(例如,SQUID)的传感器和(2)比较器(例如,模数转换器); 使用这种检测器的测量系统; 以及使用这种检测器和测量系统的方法。 检测器可以是例如数字SQUID。 检测器还可以包括用于读出比较器的输出的读出电路。 在本发明的一个方面,传感器或传感器和读出电路都由DC电流源供电。 通过使用DC电流源,可以提供例如数字SQUID,其具有减少的串扰和减小地电势的波动,并且防止噪声或错误操作的增加。
