15 pages, TeX. This 1993 preprint, together with its shorter version (A potentially realizable quantum computer, Science 261, 1569, 1993) shows how a scalable universal quantum computer could be constructed using optical or magnetic resonance

Arrays of weakly-coupled quantum systems can be made to compute by subjecting them to a sequence of electromagnetic pulses of well-defined frequency and length. Such pulsed arrays are true quantum computers: bits can be placed in superpositions of 0 and 1, logical operations take place coherently, and dissipation is required only for error correction. Programming such computers is accomplished by selecting the proper sequence of pulses.
