Gaussian conversion protocols forcubic phase state generation
Licentiatavhandling, 2021

This licentiate thesis will introduce the background of the appended paper. The scope of this thesis is to find a Gaussian conversion protocol that allows one to prepare cubic phase states, which are resourceful states for achieving universality in continuous-variable quantum computation. The starting point of the protocol is a trisqueezed state, which has been realized experimentally with superconducting microwave circuits. With the help of machine learning, large fidelity can be achieved in these protocols. Furthermore, these protocols could also be helpful for other applications in continuous-variable systems as well.
