"emit stream of single identical photons... easy to control qubits and enter and extract data... ordinary mirrors and optical detectors would be all that was needed... The preparation of those photons is the key thing. Each photon has to precisely match the quantum characteristics of the one before, and so on. Once that perfect matching is achieved... interact photons with each other., indistinguishability is crucial... solution spun onto glass surface... optically based quantum computers, quantum teleportation communication"
