Simpler quantum computer made with currently available components uses single atom to manipulate photons

"laser manipulates single atom modifying photon's state via quantum teleportation... atom can be reset/ reused for many quantum gates, reducing complexity to only: fiber optic cable, beam splitter, pair of optical switches, optical cavity, memory storage ring of circulating photons (1 photon = 1 qubit, direction = 0 , 1, 0/1 at same time if multiple directions simultaneously)... direct photon to scattering unit cavity containing single atom... photon/ atom entangle, photon returns to storage ring, laser alters atom's state"
