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
Graphene, an isolated single atomic layer of graphite, is an ideal two-dimensional system. This new electronic system exhibits a number of unique transport properties. Our current research deals with transport measurements on ultra thin layer of graphite epitaxially grown on single-crystal silicon carbide.
We study the transport properties and realize devices using the surface states of a 3D topological insulator.
We are interested in studying spin glass phase dynamics in metals in using mesoscopic probe.
We are interested in studying phase slips and the conjugate of the Josephson effect in superconducting circuits and how to use them in metrology to define a current standards.
