"entangle resting with flying qubits in form of photons, with ultracold rubidium atoms connected in parallel sandwiched between 2 almost perfect mirrors, 1 slightly more transparent so photon leaves in precisely predetermined direction, coupling into optical fiber... individually control up to 6 atoms and entangle each with a photon, using optical tweezers... multiplexing maintains entanglement, works almost 100% of time/ almost deterministically, scalable to considerably more qubits... distributed networks, quantum internet"
