论文摘要
直流电流（DC）超导量子干扰装置（SQUID）的脉冲读数对于需要在Millikelvin温度下进行的实验，例如超导和电子自旋Qubits的读数至关重要。这些实验中使用的脉冲读数算法通常特定于实验设置，需要优化。我们提出了一个模拟DC平台行为的电路，以便在室温下开发和评估脉冲读数算法，而无需运行稀释冰箱。这款新颖的电路还构成了一种低成本设备，可用于教授旨在培训下一代量子工程师的课程中DC平台的原理。
Pulsed readout of Direct Current (DC) SUperconducting Quantum Interference Device (SQUID) is crucial for experiments which need to be performed at millikelvin temperatures, such as the readout of superconducting and electron spin based qubits. Pulsed readout algorithms used in these experiments are usually specific to the experimental setup and require some optimization. We present a circuit that emulates the behavior of a DC-SQUID in order to allow the development and evaluation of pulsed readout algorithms at room temperature without the need of a running dilution refrigerator. This novel circuit also constitutes a low cost device which can be used to teach the principles of a DC-SQUID in courses aimed at training the next generation of quantum engineers.
