IBM has developed a technique dubbed “zero-noise extrapolation” that mitigates the noise of quantum computations. It might seem counterintuitive, but by repeating the computation at varying levels of ...
Journal of Computational Mathematics, Vol. 26, No. 2 (March 2008), pp. 227-239 (13 pages) We discuss semiconvergence of the extrapolated iterative methods for solving singular linear systems. We ...
