摘要：
We theoretically discuss a quantum-dot quantum computer based on charged states. The tunneling Hamiltonian of a weakly coupled quantum-dot array in the Coulomb blockade region is shown to be reduced that of nuclear magnetic resonance spectroscopy. We numerically discuss the region in which this scheme is realized. We also discuss a measurement procedure using a field-effect transistor structure. (C) 2002 Elsevier Science Ltd.
