Arqit Quantum Inc. ARQQ

Equity Insider News Commentary - Some of the most sensitive data intercepted today may not be read for years. The threat, known in security circles as 'harvest now, decrypt later', is that encrypted financial, government and health records captured now can simply be stored until a sufficiently capable quantum computer is able to break the public-key encryption protecting them. No quantum computer can do that today, but the prospect has already turned encryption upgrades into present-day work. Th

LONDON, Sept. 22, 2026 (GLOBE NEWSWIRE) -- Babcock International Group (Babcock), the defence company, has demonstrated its systems integration expertise by securely transferring scenario data using advanced encryption technology from Arqit Quantum Inc, a global leader in quantum-safe encryption, helping safeguard sensitive information from future cyber threats. Data was collected at one site in Millbrook at DVD 2026, encrypted by Arqit software and securely transmitted to Babcock's Ground Deplo

Equity Insider News Commentary – A satellite launched this year may still be flying in the 2040s.

American News Group News Commentary - Ask a large enterprise a deceptively simple question, where is your cryptography, and most cannot answer it. Encryption is buried across servers, applications, cloud systems, certificates, network devices, APIs and third-party software, often invisible to the very teams responsible for securing it. That blind spot is about to become a serious liability, because the entire foundation of digital encryption is on a countdown toward a quantum-computing reckoning
