Canada's National Research Council is allocating over $900 million to develop and commercialize quantum technologies for defence applications, including quantum computing, communications, and sensing capabilities. This investment aims to enhance the Canadian Armed Forces' capabilities in code-breaking, secure key distribution, and detecting various forms of energy. The development of quantum computing will enable the integration of artificial intelligence, while quantum communications will provide secure key distribution and anti-jamming capabilities. Quantum sensors will be used to detect electric, magnetic, and gravitational fields1. This significant investment underscores the importance of quantum technology in modern defence strategies. The development of these capabilities will have a significant impact on the country's security and sovereignty. As quantum technology advances, the need for cryptographic migration to post-quantum cryptography becomes more urgent, making it essential for practitioners to prioritize planning and implementation to ensure the long-term security of their systems.
