# Prof. Dr. Matteo Mariantoni

- Alumnus/Alumna: Quantum Systems

**Matteo Mariantoni** was Member of the Gross group at WMI as a Ph.D. student between 2003 and 2009.

**Ph.D. Thesis**: New Trends in Superconducting Circuit Quantum Electrodynamics: Two Amplifiers, Two Resonators, and Two Photons (2009)

In his Ph.D. thesis, Matteo Mariantoni studied the interaction between matter and light, which represents a fundamental process in physics. He investigate both theoretically and experimentally light-matter interaction by pursuing three different paths, which are all related to the realm of superconducting circuit quantum electrodynamics (QED). First, he measured the statistical properties of vacuum fluctuations at microwave frequencies. He realized this measurement by means of a cross-correlation homodyne detection scheme, which he has developed. Second, he proposed the implementation of a two-resonator circuit QED setup, where two resonators are coupled to one superconducting qubit. Third, he studied the symmetry properties and selection rules of a circuit QED system based on a flux qubit and analyzed the up-conversion dynamics associated with a two-photon Jaynes-Cummings-type interaction.

In 2009 he left WMI to become a Elings Prize Fellow of the California NanoSystem Institue - CNSI, working in the group of John Martinis. In 2013 he became Professor of Physics at the University of Waterloo (Institute for Quantum Computing (IQC) and Department of Physics and Astronomy). In the same year, he was awarded an Alfred P. Sloan Research Fellowship in recognition of his distinguished performance and unique potential to make substantial contributions to his field. In 2014, he was also awarded the Ontario Early Researcher Award, as well as the Kavli Fellowship.
