Mechanical resonators are systems which present high quality factors and can easily couple to a wide variety of forces. This makes them promising candidates for quantum information and sensing platforms. Recently, carbon nanotubes have been operated in the ultrastrong coupling regime, in which the presence of an electronic two level system induces an anharmonicity on the mechanical energy eigenstates. This anharmonicity opens the possibility for the control and read-out of a nanomechanical qubit. In this talk, insights on the device fabrication, transport measurements in the single and double quantum dot regimes, and the qubit read-out via reflectrometry with a superconducting cavity, will be provided, which is in the current route towards the demonstration of the mechanical qubit.
