We succeeded in the demonstration of the first quantum communication experiment from space, receiving information from the satellite in a single-photon regime in an optical ground station in Koganei city. SOTA weighs 6 kg and its size is 17.8 cm length, 11.4 cm width and 26.8 cm height. It transmits a laser signal to the ground at a rate of 10 million bits per second from an altitude of 600 km at a speed of 7 km\/s. We succeeded in correctly detecting the communication signal from SOTA moving at this fast speed. This is a major step toward building a global long-haul and truly secure satellite communication network.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>NICT developed the world&#8217;s smallest and lightest quantum communication transmitter (SOTA) onboard the microsatellite SOCRATES.
