Research Interests

Andrea is a condensed-matter physicist and an electrical engineer, with a long standing interest in the quantum dynamics of spins in nanostructures. He started his career at the Grenoble High Magnetic Field Laboratory, investigating the magnetic phase diagram of high-Tc superconductors. He then moved to the Kamerlingh Onnes Laboratory, where he did some pioneering work on the dynamics of the nuclear spin bath in quantum nanomagnets. The implications of that work for the more general problem of decoherence in large quantum systems have brought him in contact with the quantum computing community, where minimizing decoherence is an essential requirement. He then spent two years at the University of British Columbia, working on the coherent tunneling of large molecular spins. In 2006, Andrea joined CQCT to apply his expertise in coherent spin control to the realization of a donor-based spin qubit in silicon.

Andrea is now the manager of the Quantum Measurement and Control Chip program. His research effort is entirely dedicated to the achievement of coherent control and readout of the spin of an individual dopant atom in silicon, which represents the main step towards a scalable silicon-based quantum computer. To this end, he employs and develops the most advanced low-temperature, high-frequency and high-field research facilities, hosted in the National Magnet Laboratory at UNSW. He also tightly collaborates with A. Dzurak for the fabrication of nanostructures (single-electron transistors, quantum dots, PIN detectors, …), with D. Jamieson and J. McCallum for single-ion implantation and materials characterization, and with L. Hollenberg for device modeling. Part of the project also involves T. Lehmann for the design of classical microelectronic circuits to interface the quantum hardware.
