    "abstract": "A potential implementation of quantum-computation schemes in\nsemiconductor-based structures is proposed. In particular, an array of quantum\ndots is shown to be an ideal quantum register for a noiseless information\nencoding. In addition to the suppression of phase-breaking processes in quantum\ndots due to the well-known phonon bottleneck, we show that a proper quantum\nencoding allows to realise a decoherence-free evolution on a time-scale long\ncompared to the femtosecond scale of modern ultrafast laser technology. This\nresult might open the way to the realization of semiconductor-based quantum\nprocessors.",
