摘要:

在光学频率下,由诸如激光器、黑体或单光子源之类的源产生的辐射通常通过使用单光子计数器分析发射光子的时间相关性来表征。然而,在微波频率下,还没有有效的单光子计数器。相反,开发良好的线性放大器允许有效测量电磁场的振幅。在这里,我们演示了如何微波单光子源的属性可以使用相关测量的发射辐射与这样的探测器的特点。我们还展示了冷却的热场存储在一个腔体中,我们检测使用的辐射在腔体的两端发射的互相关测量的效果。

英文摘要:

At optical frequencies the radiation produced by a source, such as a laser, a black body or a single photon source, is frequently characterized by analyzing the temporal correlations of emitted photons using single photon counters. At microwave frequencies, however, there are no efficient single photon counters yet. Instead, well developed linear amplifiers allow for efficient measurement of the amplitude of an electromagnetic field. Here, we demonstrate how the properties of a microwave single photon source can be characterized using correlation measurements of the emitted radiation with such detectors. We also demonstrate the cooling of a thermal field stored in a cavity, an effect which we detect using a cross-correlation measurement of the radiation emitted at the two ends of the cavity.
