First proof-of-principle experiment of quantum repeaters with all photonics

Prof. Takashi Yamamoto, Assistant Prof. Rikizo Ituta and Guest Prof. Nobuyuki Imoto of our division have succeeded in demonstrating a first proof-of-principle experiment of quantum repeaters, by adopting all-photonic quantum repeater protocol which enables a global quantum network only with optical devices.

This research result is published in the journal Nature Communications, at 10:00 London time (GMT) on 28th January, 2019, with the following detail:
