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.
