DiVincenzo and Daniel Loss and M. S. Sherwin and Alex Small}, journal={Physical Review Letters}, year={1999}, volume={83}, pages={4204-4207} }

The electronic spin degrees of freedom in semiconductors typically have decoherence times that are several orders of magnitude longer than other relevant time scales. A solid-state quantum computer based on localized electron spins as qubits is therefore of potential interest. Here, a scheme that realizes controlled interactions between two distant quantum dot spins is proposed. The effective long-range interaction is mediated by the vacuum field of a high finesse microcavity. By using…
