David Williams Arqit Founder said, “Solving one of the biggest technology problems of the era and changing the way that significant parts of the World does encryption is a very large challenge. Arqit software is unique in doing this through symmetric key agreement and rotating authentication at end points in a manner which is not only quantum safe but also compliant with

Notes to Editors
The
UK National Cyber Security Centre (NCSC): “A quantum computer will allow the attacker to read information that has been encrypted in the past, and forge information in the future” (NCSC, Preparing for Quantum-Safe Cryptography whitepaper,11 November 2020 , link).
“Store-now, decrypt-later” is a known threat and concerning for data with a long-time value:
UK National Cyber Security Centre (NCSC): “The threat to key agreement is that an adversary collecting encrypted data today would be able to decrypt it in future, should they have access to a CRQC [Cryptographically Relevant Quantum Computer]” (NCSC, Preparing for Quantum-Safe Cryptography whitepaper,11 November 2020 , link).US Congress : “The rapid progress of quantum computing suggests the potential for adversaries ofthe United States to steal sensitive encrypted data today using classical computers and wait until sufficiently powerful quantum systems are available to decrypt it” (Congress , Quantum Computing Cybersecurity Preparedness Act,21 December 2022 , link).
Symmetric cryptography is a solution that can be implemented right now and can be used for both encryption and key exchange:
UK National Cyber Security Centre (NCSC): “In contrast with PKC [public-key cryptography], the security of symmetric cryptography is not significantly impacted by quantum computers, and existing symmetric algorithms with at least 128-bit keys (such as AES) can continue to be used” (NCSC, Next steps in preparing for post-quantum cryptography,3 November 2023 , link).US National Security Agency (NSA): “NSA considers using pre-shared symmetric keys in a standards-compliant fashion a better near-term post-quantum solution than implementing experimental post-quantum asymmetric algorithms” (NSA , The Commercial National Security Algorithm Suite 2.0 and Quantum Computing,7 September 2022 , link).

White House : “ByDecember 31, 2023 , agencies maintaining NSS shall implement symmetric-key protections (e.g., High Assurance Internet Protocol Encryptor (HAIPE) exclusion keys or VPN symmetric key solutions) to provide additional protection for quantum-vulnerable key exchanges” (TheWhite House , National Security Memorandum on Promoting United States Leadership in Quantum Computing While Mitigating Risks to Vulnerable Cryptographic Systems,4 May 2022 , link).
