Thesis Project : Title, Summary
"Decoherence in superconducting quantum circuits"

The project aims at a deeper understanding of quantum circuitries made of the high critical temperature superconductor (HTS) YBa2Cu3O7-x with potential applications ranging from quantum computing to solid-state physics research in previously
inaccessible regimes.
The focus will be on material specific decoherence effects coming from the dielectrics involved in the fabrication process and the
superconductor itself.
In the latter case the project will be devoted to the experimental investigation of the low temperature excitation spectra of HTS by using two-level quantum systems. We will use a HTS Josephson junction, acting as a two level system, embedded in a superconducting resonator (see Fig. 1). This experiment will deliver detailed information about the quasiparticle spectrum of HTS, giving access to unresolved issues on the nature of superconductivity in these materials.
