Superconducting Circuits and Quantum Computation—T. P. Orlando
... Additionally, no periodic variation of population with varying pulse duration was observed. In a simple two-level system, observing such a gap would be unexpected for an incoherent transition, since the population in the lower level should always be larger than 0.5 in that case. In order to address ...

Quantum Optical Multiple Scattering
... This thesis concerns the theoretical investigation of interference phenomena related to elastic and inelastic scattering of quantized light. The presented work is naturally divided into two parts, the first is concerning elastic scattering while the second explores inelastic scattering. In the first ...
