In microelectronics, while quantum mechanics can explain the properties of materials (conductors, insulators, etc.), the electrodynamics of circuits remains classical. However, when electronic devices become comparable in size to atoms, or when exploring the properties of systems at very low temperatures, a new situation arises: electronic quantum coherence, which extends to the entire device and can influence its collective behavior.
The research carried out by the SPEC Nanoelectronics team focuses mainly on the study of:
- flying qubits in ballistic quantum conductors (electronic quantum optics), levitons
- graphene-based quantum circuits, electrical and thermal conductivity
- high-frequency quantum transport (current, noise),
