Imperfection effects for multiple applications of the quantum wavelet transform
arXiv:quant-ph/0303043 · doi:10.1103/PhysRevLett.90.257902
Abstract
We study analytically and numerically the effects of various imperfections in a quantum computation of a simple dynamical model based on the Quantum Wavelet Transform (QWT). The results for fidelity timescales, obtained for a large range of error amplitudes and number of qubits, imply that for static imperfections the threshold for fault-tolerant quantum computation is decreased by a few orders of magnitude compared to the case of random errors.
