Abstract
A model of a quantum computer with diagonal continuous interaction between qubits is proposed. Such a computer is controlled only by short single-qubit operations. The realization of quantum Fourier transform and simulation of the wave function of a many-particle problem with linear and quadratic potentials on this quantum computer are discussed. This method applies to a wide class of diagonal interactions and to the case, where the interactions of different qubits are different.
