We propose to study the interaction between mechanical and electronic degrees of freedom using a Superconducting Quantum Interference Device (SQUID) based on a single suspended carbon nanotube. The project can evolve toward two main directions. The first one aims at observing and generating mechanical quantum states of the carbon nanotube such as Schrödinger cat. The other direction focuses on the study of the dynamics of a single molecular magnet  using the nanotube-SQUID as an ultra-sensitive magnetometer.

The goal of the project is to study the spin-phonon coupling between a single molecular magnet and the bending modes of a suspended carbon nanotube. A suspended nanotube is a near ideal environment for the spin of the molecule, and it allows to control its phononic environment, which is expected to result in very long coherence time of the molecular spin. This project relies on the realization of a double quantum dot circuit within the carbon nanotube enhancing the scope of experimental exploration, one example being the ground state cooling of the carbon nanotube vibration.
