论文摘要
我们应用量子轨迹技术来分析与电阻器形成的热浴相结合的超导量子标式的现实设置，该系统可在分析中使用相关过渡速率的显式表达式。我们讨论了跳跃轨迹的主要特征，并将它们与使用电阻器作为纳米级别的荧光测量的预期结果（“点击”）相关联。作为主要的实际结果，我们提出了一个模型，该模型可以预测由单个微波光子约为逼真的量热计的时间域响应，并融合了由于温度计吸收器和有限的带宽的基本热波动而引起的固有噪声。
We apply quantum trajectory techniques to analyze a realistic set-up of a superconducting qubit coupled to a heat bath formed by a resistor, a system that yields explicit expressions of the relevant transition rates to be used in the analysis. We discuss the main characteristics of the jump trajectories and relate them to the expected outcomes ("clicks") of a fluorescence measurement using the resistor as a nanocalorimeter. As the main practical outcome we present a model that predicts the time-domain response of a realistic calorimeter subject to single microwave photons, incorporating the intrinsic noise due to the fundamental thermal fluctuations of the absorber and finite bandwidth of a thermometer.
