Quantum technologies

The search for suitable physical platforms for implementing quantum computing is a very active research topic and at the heart of the national strategy. Elementary quantum machines with a few hundred imperfect physical qubits are gradually becoming available, based on several systems (superconducting qubits, ion traps, photons, trapped neutral atoms). However, error-tolerant quantum computing is not yet mature. In this context, we believe that fundamental research on alternative qubits is still useful, even if they are currently far from being the most advanced quantum systems. The department therefore proposes a variety of topics using doped molecules and nanocrystals to propose credible and robust alternatives for qubit intelligence.

1. Molecular spin manipulation for quantum information

2. Lanthanide-doped nanocrystals for quantum information

3. Single-photon sources based on colloidal nanocrystals

4. 2D/0D semiconductors for quantum technologies
