These superconducting quantum circuits based on Josephson junctions appear as model systems to study quantum phenomena in electronic systems. The current research deals with superconducting quantum bits (phase qubit, two interacting qubits and a topologically protected qubit), quantum phase slip processes in Josephson junctions chains and the development of a current standard and nanorefrigerator.
We are interested in studying the dynamics and the coherence properties of a single electron transfered between two distant quantum dots in AlGaAs heterostructures. Possible applications : quantum spintronics and quantum computation.
We are interested in performing quantum optics experiment with single flying electrons.
Nanomechanical devices are designed to probe superconducting silicon and other new materials
We are interested in studying coherent quantum phase-slip dynamics in Josephson junction chains and their potential application for quantum metrology.
