The SQC group is active in the field of Quantum computing with superconducting devices, in particular phase and flux qubits based on SQUIDs, and in fields related to these topics.

The IFN is an institute of the Italian CNR devoted to the study and fabrication of advanced devices for photonics, optoelectronics and electronics. Nanotechnologies play a prominent role in these research fields. The combined expertise in nanofabrication, materials and photonics creates a synergy able to compete in this very new and challenging field.
