Present‐day information processing is based on the rules of classical physics. If the ubiquitous superposition principle of quantum mechanics could be harnessed, quite different and surprising rules would be at our disposal. They would give rise to the celebrated quantum parallelism allowing, e.g. for an increased efficiency of quantum over classical computing. To achieve this goal there are at least two different paradigms which could be exploited: ‘selective control’ and ‘collective control’. The latter should be an interesting alternative for nanoscopic quantum networks. Copyright © 2001 John Wiley & Sons, Ltd.
