US Patent 7805031 - Defect-tolerant quantum computer

In quantum computing "color centers" refer to atomic vacancies embedded in diamond which may be used as quantum bits. This patent from HP proposes a way to fabricate a photonic type of quantum computer based on such color centers which is tolerant to defects. Claim 1 reads: 

1. A method for fabricating a defect-tolerant quantum computer architecture, the method comprising:

depositing a transmission layer on a substrate surface;

depositing a nucleation center at a particular location on the transmission layer;

forming photonic devices in the transmission layer, the photonic devices configured to transmit electromagnetic waves;

forming a color center in diamond at the nucleation center; and

embedding the transmission layer and the color center between a top cladding layer and a bottom cladding layer.
