Engineering and detecting microwave photons
Licentiatavhandling, 2015

Microwave quantum optics using superconducting circuits, also known as circuit QED, is a recent and promising field to study light-matter interactions at the fundamental level. In this field, artificial atoms made of superconducting elements interact with microwave photons routed through one dimensional transmission lines. This thesis is under the purview of circuit QED and is based on the three appended papers. In these three articles, we look at the problems of engineering photon-photon interaction (a la cross-Kerr effect) in microwaves using an artificial atom, storing and retrieving microwave photons using a tunable cavity and finally detecting a single propagating microwave photon non-destructively. The analysis is done using the framework of open quantum systems, where we use master equations and stochastic master equations to study the evolution of these artificial atoms in the presence of environment and under measurements respectively.
