Prof. François Sfigakis
Francois obtained his PhD at the University of Cambridge, investigating single electron pumps, Kondo physics, and the 0.7 structure in GaAs 2DEGs. Prior to joining IQC, he was a Senior Research Associate at the University of Cambridge, where his work included the non-Abelian fractional quantum Hall effect, quantum-dot-based qubits, spin FETs, and electron-hole interactions in coupled bilayers. In 2018, Francois became a Research Assistant Professor in Jonathan Baugh’s group at IQC, to work on developing Si CMOS qubits, topological qubits in two-dimensional electron gases, single photon sources (all-electric, on-demand, and high-rate), and III-V infrared photo-detectors. In 2024, he joined the QPD group to work on quantum optoelectronics (on-demand single/entangled photon sources, and single photon detectors) and quantum metrology (to redefine the Ampère and the quantum Candela).
