QKD from a microsatellite: the SOTA experience
Alberto Carrasco-Casado, Hideki Takenaka, Mikio Fujiwara +3
The transmission and reception of polarized quantum-limited signals from space is of capital interest for a variety of fundamental-physics experiments and quantum-communication pro…
LEO-to-ground optical communications using SOTA (Small Optical TrAnsponder) - Payload verification results and experiments on space quantum communications
Alberto Carrasco-Casado, Hideki Takenaka, Dimitar Kolev +8
Free-space optical communications have held the promise of revolutionizing space communications for a long time. The benefits of increasing the bitrate while reducing the volume, m…
Satellite-to-ground quantum communication using a 50-kg-class micro-satellite
Hideki Takenaka, Alberto Carrasco-Casado, Mikio Fujiwara +3
Recent rapid growth in the number of satellite-constellation programs for remote sensing and communications, thanks to the availability of small-size and low-cost satellites, provi…
Free-space optical channel estimation for physical layer security
Hiroyuki Endo, Mikio Fujiwara, Mitsuo Kitamura +10
We present experimental data on message transmission in a free-space optical (FSO) link at an eye-safe wavelength, using a testbed consisting of one sender and two receiver termina…
