AHMEDABAD, India (ISRO PR) — On 27 January 2022, scientists from the two premier laboratories of Department of Space (DOS), viz. Space Applications Centre (SAC) and Physical Research Laboratory (PRL), both from the city of Ahmedabad, have jointly demonstrated quantum entanglement based real time Quantum Key Distribution (QKD) over 300m atmospheric channel along with quantum-secure text, image transmission and quantum-assisted two-way video calling.
BENGALURU, India (ISRO PR) — For the first time in the country, Indian Space Research Organisation (ISRO) has successfully demonstrated free-space Quantum Communication over a distance of 300 m.
A number of key technologies were developed indigenously to accomplish this major feat, which included the use of indigenously developed NAVIC receiver for time synchronization between the transmitter and receiver modules, and gimbal mechanism systems instead of bulky large-aperture telescopes for optical alignment.
SAN FRANCISCO, CA, August 4, 2020 — Loft Orbital Solutions Inc (Loft Orbital) has signed a contract with Honeywell to provide launch service and satellite bus for the Canadian Space Agency’s (CSA) Quantum EncrYption and Science Satellite (QEYSSat) mission, for which Honeywell is the prime contractor.
The QEYSSat mission will demonstrate Quantum Key Distribution (QKD), a groundbreaking technology that has the potential to revolutionize encrypted communications. To date, the first and only space-based QKD demonstration has been performed by the Chinese Micius spacecraft in 2017.
