By the 2030s, quantum computers might compromise traditional cryptography, putting digital infrastructure at high risk in the European Union (EU) and around the world. Specifically, it is expected that quantum computers' unique capabilities will allow them to solve complex mathematical problems, such as breaking the traditional cryptographic systems used universally. The confidentiality, integrity and authenticity of sensitive data – including health, financial, security and defence information – will be exposed to threats from any actor possessing a sufficiently powerful quantum computer. There is a pressing need for the EU to start preparing its digital assets to face this risk. Post-quantum cryptography (which uses classical computer properties) and quantum cryptography (which uses quantum mechanical properties) are the two types of critical technology able to protect digital infrastructure from quantum computer attacks. Robust post-quantum cryptography algorithms have been identified, but swift and efficient implementation is crucial before malicious actors exploit the power of quantum computers. Experts stress the need for quantum preparedness to be put in place now, with some of them even warning of a 'quantum cybersecurity Armageddon'. Several countries are adopting strategies to address post-quantum cryptography. The EU is working with Member States and the United States to speed up the transition to post-quantum cryptography, and is also exploring long-term quantum cryptography initiatives.
