Ontario startup aims to solve what may be the biggest threat to globally secure communication

▤ Summary

QEYnet is building a space-based quantum key distribution system to protect communications from future quantum-computing attacks. The Ontario startup says it can send encryption keys from microsatellites to Earth using quantum particles, making interception detectable. The company has already secured government-backed support and plans to launch an orbital demonstration satellite in 2027. The article frames the technology as a long-term answer for banks, utilities, defense, and other critical infrastructure providers that need stronger communication security.
