DOI: 10.1038/s41567-019-0585-6

Abstract: Efficient excitation of a single two-level system usually requires that the driving field is at the same frequency as the atomic transition. However, the scattered laser light in solid-state implementations can dominate over the single… read more here.

DOI: 10.1038/s41598-019-44940-7

Abstract: The coherent volume of single quantum states of matter is typically smaller than that of photons by several orders of magnitude, and hence, interactions between photons and single quantum states are normally very weak. This… read more here.
