Nuclear spin states in molecules will be proposed to act as quantum registers for Quantum Computing (QC).

The Hilbert space spanned by the the nuclear spins will be engineered synthetically and addressed both electrically and optically, partially at the single molecule level.1-13 Finally, Grover ´s quantum search algorithm will be implemented on the nuclear spin register of a TbPc2 Qudit.10
