✦ Synopsis

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.

We discuss a mechanism for generating a maximum entangled state (Greenberger-Horne-Zeilinger (GHZ)) in a coupled quantum dots system, based on analytical techniques. The reliable generation of such states is crucial for implementing solid-state based quantum information schemes. The signature origin
