      abstract     = {Molecular nanomagnets are attractive candidate qubits
                      because of their wide inter- and intra-molecular tunability.
                      Uniform magnetic pulses could be exploited to implement one-
                      and two-qubit gates in presence of a properly engineered
                      pattern of interactions, but the synthesis of suitable and
                      potentially scalable supramolecular complexes has proven a
                      very hard task. Indeed, no quantum algorithms have ever been
                      implemented, not even a proof-of-principle two-qubit gate.
                      Here we show that the magnetic couplings in two
                      supramolecular {Cr7Ni}-Ni-{Cr7Ni} assemblies can be
                      chemically engineered to fit the above requisites for
                      conditional gates with no need of local control. Microscopic
                      parameters are determined by a recently developed many-body
                      ab-initio approach and used to simulate quantum gates. We
                      find that these systems are optimal for proof-of-principle
                      two-qubit experiments and can be exploited as building
                      blocks of scalable architectures for quantum simulation.},
