摘要： The states of matter systems (110) having only one basis state that couples to an excited state can be entangled using measurements of photons during transitions from the excited state. High fidelity of the entanglement can be achieved by repeating the measurements after performing bit flips on the matter systems (110). High efficiency of entanglement operation can be achieved using non-absorbing parity measurements on the emitted photons so that measured photons can be subsequently manipulated and measured to near-deterministically produce entangled states. Such entanglement operations can be employed to construct cluster states suitable for simulating arbitrary logic networks.
