Query: Optimized protocol to create repeater graph states for all-photonic
  quantum repeater   All-photonic quantum repeater is not yet commercially applicable due to
difficulty in the generation of repeater graph states (RGS) and the
probabilistic nature of Bell-state measurement. In recent years, several
deterministic protocols have been proposed to generate RGS. However, they can
only create bare RGS and a rate-distance analysis for the deterministic
approach is currently missing. We present a deterministic generation scheme of
encoded RGS and show that after optimization, the repeater using our scheme
performs at least 4.9 times better than the traditional probabilistic
generation scheme in terms of secret key rate, with a significant reduction in
the total number photons by 2 orders of magnitude. The duration of our
generation protocol is only half of the existing deterministic schemes. We also
describe in detail an experimental method using cavity QED-enhanced resonance
fluorescence and time-bin encoding to implement our protocol.
