arXiv:quant-ph/0202030 · doi:10.1134/1.1577767
Abstract
It is proved that a quantum computer with fixed and permanent interaction of diagonal type between qubits proposed in the work quant-ph/0201132 is universal. Such computer is controlled only by one-qubit quick transformations, and this makes it feasible.
