Ontario startup aims to solve what may be the biggest threat to globally secure communication (opens original article in a new tab)

An Ontario startup is developing a quantum-based method to securely transmit encryption keys from space, aiming to protect against future threats from quantum computing by using satellites to overcome limitations of current terrestrial networks.

• Ontario startup QEYnet is developing a method to securely transmit encryption keys from space using quantum particles.
• Quantum key distribution (QKD) uses quantum physics to create encryption keys sensitive to eavesdropping, with satellites overcoming limitations of terrestrial-fibre networks.
• QEYnet aims to create a global QKD network using microsatellites and has received funding from the Canadian Space Agency and Department of National Defence.
