Space Station to Host ‘Self-Healing’ Quantum Communications Tech Demo

SEAQUE will be hosted on the International Space Station by the Nanoracks Bishop airlock. The blue-and-gold brackets attached to the side of the airlock are for external payloads. The technology demonstration will be installed at one of those sites. (Credit: NASA)

The NASA-funded experiment will test two technologies that could eventually enable quantum computers to communicate with each other no matter where they are located.

PASADENA, Calif. (NASA PR) — A tiny experiment launching to the International Space Station later this year could set the stage for a future global quantum network. Called the Space Entanglement and Annealing QUantum Experiment (or SEAQUE), the milk-carton-size technology demonstration will test two communications technologies in the harsh environment of space.


SpeQtral Announces SpeQtral-1 Quantum Satellite Mission for Ultra-secure Communications

SpeQtral-1 will perform trusted node quantum key distribution over intercontinental distances with partners globally

SINGAPORE, Feb. 9, 2022 (SpeQtral PR) — SpeQtral, an emerging leader in quantum-secure communication systems, announces today at the Global Space and Technology Convention, the official kickoff of its forthcoming Quantum Key Distribution (“QKD”) satellite mission in space, SpeQtral-1.

The SpeQtral-1 satellite is expected to be launched in 2024, and is primed to be one of the first few QKD satellite missions to be launched by a commercial entity. It will demonstrate the technological feasibility of intercontinental out-of-band symmetric key delivery with a focus on addressing practical commercial requirements of end users. In this commercial pilot phase, entities interested in securing their data communications with QKD would be able to use SpeQtral-1 to receive quantum keys.
