Although early demonstrations of quantum computing explored a wide
variety of experimental methods, quantum computers based on solid-state
systems, in spite of the potentially larger interactions limiting
coherence, are believed to be worth serious investigation. Systems based
on Josephson Junctions, electrons resident on the surface of superfluid
Helium, compound semiconductors, electrons trapped in an acoustic wave,
semiconductor quantum dots coupled via electromagnetic field, and
solid-state nuclear magnetic resonance systems that have been proposed
are described below. Previously we have investigated coherent coupling
of electrons trapped at neighboring asymmetric quantum dots in a III-V
pillar structure. However, we believe the best candidate is based on the
coupled spin of electrons on trapped on adjacent quantum dots in a
silicon environment currently being investigated in our research.
