Research activities:

We are designing, synthesising and studying single molecule-machines working for mechanics or logic [1]. Those functions are embedded on a molecule and studied by LT-UHV-STM, UHV-NC-AFM and soon in a planar UHV technology with an atomic scale precision for surface atomic circuit or molecule-logic gates [2]. Our mechanical molecules are gears (1.2 nm in diameter) [3], motors (1.5 nm in diameter) [4] and cars (board 1.5 nm long, wheel 0.8 nm in diameter)) [5]. Their quantum control is actively explored [6]. Our molecule-logic gates are working on a semi-classical basis (molecule designed like an electrical circuit) [7] or quantum mechanically [8]. In this case, the quantum control is resulting from classical binary access to the molecule (modifying the Hamiltonian (QHC)) [9] or from a quantum input (via the state vector by structuring the molecule in qubits).
