d-wave just announced a public demo for an 16-qubit superconducting adiabatic quantum computer on rose.blog. I haven’t read the recommended papers yet but as far as I understood it is realized by a set of SQUIDs in a 4×4 array. Should next read the arxiv paper: arxiv.org/pdf/quant-ph/0211152.
Will post some more about this promissing and scalable approach for commercial quantum computation applications as soon as I finished my diploma thesis on experimental quantum information coding in polarisation-entangled photon states.
