Coherent manipulation of spin qubits based on polyoxometalates: the case of the single ion magnet [GdW$_{30}$P$_5$O$_{110}$]$^{12-}$

Abstract

Polyoxometalate single ion magnet [GdW$_{30}$P$_5$O$_{110}$]$^{12-}$ has been studied by generalized Rabi oscillation experiments. It was possible to increase the number of coherent rotations tenfold through matching the Rabi frequency with the frequency of the proton. Achieving high coherence with polyoxometalate chemistry, we show their excellent potential not only for the storage of quantum information but even for the realization of quantum algorithms.
