Matteo Mariantoni
Matteo Mariantoni is an Associate Professor at the Institute for Quantum Computing and the Department of Physics and Astronomy at theUniversity of Waterloo, where he has been based since 2013. He leads the Laboratory for Digital Quantum Matter and is also a faculty member of the Institute for Quantum Computing. His work focuses on quantum computing systems, particularly those based on superconducting quantum circuits.
Mariantoni has a strong research background in superconducting qubits and circuit quantum electrodynamics. His expertise includes low-level microwave detection, pulsing techniques, and the measurement of very weak quantum signals generated by superconducting qubits coupled to on-chip resonators. His research interests cover quantum computing, quantum error correction, digital quantum emulations, superconducting quantum circuits, and broader quantum science. His work combines experimental research with selected theoretical studies.
He completed his PhD in Physics in 2009 at theTechnical University of Munich, while working at the Walther-Meissner Institute for Low Temperature Research. His doctoral thesis focused on superconducting circuit quantum electrodynamics and examined light–matter interaction through vacuum fluctuation measurements, multi-resonator circuit QED systems, and two-photon interactions. He also holds a Master of Science degree in Physics from Chalmers University of Technology in Sweden and received engineering training through Politecnico di Milano.
After his doctorate, Mariantoni joined the California NanoSystems Institute at theUniversity of California, Santa Barbara, as an Elings Prize Fellow, working in the group of John Martinis. During this period, his work on a single-chip quantum memory and processor using a quantum von Neumann architecture was recognised byPhysics Worldas one of the top ten breakthroughs of 2011.
At the University of Waterloo, his team has fabricated advanced superconducting resonators and transmon qubits with high coherence and gate fidelities above 99.9 per cent. In 2015, his group developed the quantum socket, a vertical wiring and packaging method for scalable quantum computing. His work also includes reducing wiring complexity in large qubit systems.
Mariantoni has received several honours, including the Alfred P. Sloan Research Fellowship and the Ontario Early Researcher Award. He actively teaches electricity and magnetism courses and has published widely in leading scientific journals on superconducting quantum circuits and quantum computing technologies.
