Novel scheme for a universal quantum computer

A scenario for realization of a quantum computer is proposed consisting of spatially distributed q-bits fabricated in a host structure where nuclear s pin-spin coupling is mediated by laser pulse controlled electron-nuclear tr ansferred hyperfine (superhyperfine) Fermi contact interaction. Operations illustrating entanglement, nonlocality, and quantum control logic operation s are presented and discussed. The notion of universality of quantum comput ation is introduced, and the irreducible conditions are presented. It is de monstrated that the proposed generic scenario for realization of a quantum computer fulfills these conditions.
