• Abstract: Quantum algorithms have shown successful results in solving noisy linear problems with quantum samples in which cryptographic hard problems are relevant. In this paper the previous results are investigated in detail, leading to new quantum and classical algorithms under the same assumptions as in the earlier works. To be specific, we present a polynomial-time quantum algorithm for solving the ring learning with errors problem with quantum samples which was deemed to be infeasible in [12], as well as polynomial-time classical algorithms that are more efficient than the corresponding quantum algorithms in solving the short integer solution problem with quantum samples and the learning with errors problem with size-reduced quantum samples.
