Post-quantum Cryptography Market: 2026-2035

An aspect of post-quantum cryptography that cannot be underestimated is its difficulty and inaccessibility in terms of understanding for non-technical staff. Although it can be simplified, without an underlying understanding of cryptography and how it can be made vulnerable using advanced quantum computers, the threat seems less tangible than more conventional threats such as identity fraud and brute-force attacks, for example. This can lead to a lack of prioritisation of measures against future quantum threats, leaving critical infrastructure vulnerable to quantum attacks. The fact that it is still unknown when ‘Q-Day’ will happen, the day on which quantum computers can crack classical encryption, is another factor impeding immediate action.
