摘要:

我们在一维开放空间中嵌入了一个人工原子-超导transmon量子比特,研究了微波相干态入射时的散射特性。通过研究反射场和透射场的统计,我们证明了散射态可以是非经典的。特别是,通过测量二阶关联函数,$g^{(2)}$,我们显示光子的反聚束在反射场和超聚束在透射场。我们还比较了弹性和非弹性散射场使用相位敏感和相位不敏感的测量。

英文摘要:

We have embedded an artificial atom, a superconducting transmon qubit, in a 1D open space and investigated the scattering properties of an incident microwave coherent state. By studying the statistics of the reflected and transmitted fields, we demonstrate that the scattered states can be nonclassical. In particular, by measuring the second-order correlation function, $g^{(2)}$, we show photon antibunching in the reflected field and superbunching in the transmitted field. We also compare the elastically and inelastically scattered fields using both phase-sensitive and phase-insensitive measurements.
