Abstract The repetition of Grover-diffusion operator the order of √N times is the essence of the Grover quantum selection algorithm. For large N the coherence time T2 of the qubits limits the application of the algorithm. We explore what other operators could be devised in its place to accelerate convergence. We present a C++ SU(2) model of the Grover-diffusion operator implemented using our SU2 package.
