%0 Journal Article %T Programming Pulse Driven Quantum Computers %A Seth Lloyd %J Physics %D 1999 %I arXiv %X 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. %U http://arxiv.org/abs/quant-ph/9912086v1
