Arqit Quantum Inc. reports news on quantum-safe cybersecurity products for governments, enterprises and telecommunications providers. The company’s updates center on post-quantum encryption, cryptographic discovery, compliance support and data-protection tools, including Encryption Intelligence, NetworkSecure and SKA-Platform technology.
Recurring developments include financial results, contract activity, product launches, technology integrations and collaborations that apply Arqit encryption to VPN services, optical networks, confidential computing and cloud-to-edge security environments. Company announcements also address post-quantum migration, data sovereignty, cryptographic inventory and risks associated with current encryption systems becoming vulnerable to quantum computing.
Arqit Quantum (Nasdaq: ARQQ) provided select preliminary, unaudited results for H1 FY2026 ended March 31, 2026. Management expects H1 revenue of approximately $620,000–$630,000 versus $67,000 in H1 FY2025. Cash and cash equivalents were $28.9 million as of March 31, 2026.
Revenue growth reflects recognition from deliveries under preexisting contracts and three new contracts signed during the period. Results are preliminary, unaudited, and may change during final close and independent review.
Arqit (Nasdaq: ARQQ) and RAD announced a collaboration on March 2, 2026 to deliver a joint quantum-safe encryption solution for telcos. The integration pairs Arqit’s NetworkSecure™ key generation with RAD’s ETX Carrier Edge platform to enable site-to-site, site-to-cloud VPNs and DCI.
The solution targets near-term risks such as "Harvest Now, Decrypt Later" attacks and the long-term threat from quantum computing by offering a crypto-agile, hybrid post-quantum approach, according to the company.
Arqit (Nasdaq: ARQQ) and Intel-sponsored research finds 62% of respondents cite data sovereignty and privacy risks as the top factor slowing AI projects in the public cloud. The survey also reports 16% of organisations have no access to facilities with guaranteed data sovereignty and only 8% have sovereign edge environments.
The research, to be unveiled at MWC Barcelona 2026, shows urgent AI demand but rollout delays: 69% rate AI for network safety as urgent, yet 60% are still testing or have not deployed AI for security. 80% expect to use confidential computing within 12 months.
Arqit (NASDAQ: ARQQ) announced that its quantum-safe encryption software is now available pre-installed inside an Intel TDX trusted execution environment on Intel NetSec Accelerator Reference Design-based cards, enabling confidential compute for trusted workloads, networks, and agents.
The solution creates on-demand, non‑stored quantum-safe keys consumed inside the TEE, protects data at line speed with hardware acceleration, and targets telecom and critical national infrastructure use cases. Arqit and Intel will demonstrate the technology at MWC Barcelona 2026 starting March 2, 2026.
Arqit (Nasdaq: ARQQ) and 6WIND announced a strategic collaboration on Feb 19, 2026 to integrate Arqit’s NetworkSecure™ quantum-safe key generation with 6WIND’s Virtual Service Router.
The joint solution targets scalable, on-device quantum-safe IPsec VPN services for telcos, enterprises, uCPE and virtualised cloud deployments.
Arqit (Nasdaq: ARQQ) on January 22, 2026 launched Encryption Intelligence, a commercial product that provides automated cryptographic discovery, continuous monitoring and risk prioritisation to support migration to post-quantum cryptography (PQC).
Encryption Intelligence aims to expose obsolete or weak encryption across networks, applications and cloud services, accelerate secure PQC migration planning, and provide ongoing optimisation for compliance. Arqit was selected to participate in the UK National Cyber Security Centre Post-Quantum Cryptography Pilot, which the company says validates its discovery and migration planning methodology.
Arqit Quantum (Nasdaq: ARQQ) reported fiscal year 2025 revenue of $530,000 for the year ended September 30, 2025, with $463,000 in the second half versus $67,000 in the first half.
Revenue arose from seven contracts (two multi-year, recurring) and the company has executed contracts expected to generate approximately $1.2 million in fiscal 2026. In the two months after year‑end Arqit signed 12 demonstration and test licenses. Operating costs averaged $2.5 million per month and cash and cash equivalents were approximately $36.9 million as of September 30, 2025. In May Arqit acquired Ampliphae’s product portfolio and innovations team to add Encryption Intelligence and AI analytics.
Arqit (NASDAQ: ARQQ) and Sparkle announced on December 3, 2025 a successful proof of concept demonstrating quantum-resistant encryption embedded at the optical transport layer across Sparkle’s metropolitan ring in Athens.
The POC applied Arqit SKA-Platform™ encryption directly on optical transponders (L1), secured multi-100G optical links end-to-end, and required no physical changes to optical hardware. Keys were injected from VM and universal CPE appliances via an ETSI14 interface and managed through an orchestration platform. The companies present the result as a scalable, low-disruption approach to protect high-capacity networks against future quantum threats.
Arqit Quantum (NASDAQ:ARQQ) will report financial results for the fiscal year ended September 30, 2025 and hold a conference call on Tuesday, December 9, 2025 at 11:00 a.m. ET.
Company CEO Andy Leaver and CFO Nick Pointon will host the call. A live webcast will be available on the company’s News & Events page at ir.arqit.uk and a replay will be posted for a limited time. Phone access requires registration via the provided link; participants are encouraged to dial in 15 minutes early.
Arqit (NASDAQ: ARQQ) launched SKA Central Controller (SKA-CC) on Nov 11, 2025, a crypto‑agile, low‑footprint software platform designed to provide quantum‑safe symmetric key management across wireline, mobile, cloud and AI environments.
SKA-CC generates dynamic symmetric keys for endpoint authentication and encrypted VPN tunnels, removes reliance on long‑lived pre‑shared keys or PKI, and supports use cases from Optical Layer 1 to APIs and private 5G—targeting Telco and Defense Managed Service Providers to enable quantum‑safe NaaS and mobile VPNs.
