Phys. Rev. Lett. 90, 257902 (2003) [4 pages]Imperfection Effects for Multiple Applications of the Quantum Wavelet TransformReceived 10 March 2003; published 26 June 2003 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. The results for fidelity time scales, 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. © 2003 The American Physical Society URL:
