Unveiling phonons in a prototype molecular quantum bit

Abstract: The two main pillars of the current research in molecular magnetism are the possibilities of exploiting molecules as classical bits in high-density magnetic memories or as qubits in quantum information processing (QIP) applications. Spin-phonon interactions are the main cause of magnetic relaxation in these molecules. However, phonons dispersion in molecular magnets have not been directly investigated yet. Here we propose to study a prototypical vanadyl complex, as vanadyl molecules are currently emerging as archetypes of a new generation of molecular qubits with long coherence times even at high temperatures. We propose to use the LET and MERLIN time of flight spectrometers to directly measure the phonon dispersions of the vanadyl complex to gain a deep understanding of the role of phonons in magnetic relaxation and dechoerence.
