摘要:

在大多数物理系统中,创建单光子训练并监测其传播和相互作用是具有挑战性的,因为光子通常与其他系统的相互作用非常弱。然而,当将微波频率光子限制在传输线谐振器中时,有效的光子-光子相互作用可以由嵌入谐振器中的量子比特介导。在这里,我们通过二阶关联函数测量观察到光子阻塞现象。实验清楚地表明反聚束在连续泵浦源的单微波光子测量使用微波分束器,线性放大器,和正交幅度检测器。我们还研究了共振荧光和瑞利散射在莫洛三重态的光谱。

英文摘要:

Creating a train of single photons and monitoring its propagation and interaction is challenging in most physical systems, as photons generally interact very weakly with other systems. However, when confining microwave frequency photons in a transmission line resonator, effective photon-photon interactions can be mediated by qubits embedded in the resonator. Here, we observe the phenomenon of photon blockade through second-order correlation function measurements. The experiments clearly demonstrate antibunching in a continuously pumped source of single microwave photons measured using microwave beam splitters, linear amplifiers, and quadrature amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering in Mollow-triplet-like spectra.
