What Squareroot8 Technologies does

Squareroot8 Technologies (SQRT8) is a Singapore-based quantum security company that develops quantum communication hardware and software for information security applications. Its core technology stack centers on Quantum Key Distribution (QKD) for physically secure key exchange and Quantum Random Number Generation (QRNG) for verifiably unpredictable entropy. The flagship product, QDice®, is described as the world's first fully integrated self-testing QRNG built on a silicon photonic chip, using a measurement-device-independent protocol that continuously certifies random bit output and aborts on performance threshold failures. QDice® is fabricated on a standard 8-inch silicon-on-insulator wafer process at Singapore's Advanced Micro Foundry and operates at room temperature, removing the cryogenic barrier to commercial deployment. The portfolio extends to SQRT8 Aegis QKD hardware, SQRT8 QRNG+PQC combining QRNG with post-quantum cryptography, and FracQtion, a joint product with Partisia that layers QRNG with Multi-Party Computation for identity, key lifecycle, and secure computation in finance, telecoms, and critical infrastructure.

SQRT8 targets governments and defense agencies, financial institutions, telecommunications operators, healthcare and pharmaceutical organizations, and critical infrastructure operators across Asia-Pacific. Distribution combines direct enterprise field sales (with a 'Request a Demo' consultative motion) with strategic partnerships: VIAVI Solutions for network test and fibre sensing channels, BW Digital for embedding into data center and submarine cable infrastructure across Singapore and Batam, Partisia for cryptographic software co-development, and Quantinuum for research-ecosystem collaboration. Revenue is generated through hardware sales (QKD and QRNG devices), subscription and usage-based 'as-a-service' offerings (QKD-Aegis-aaS, QRNG+PQC-aaS, Quantum Safe Managed Data Center Services, Cybersecurity + Quantum Security Services), professional and advisory services for quantum-safe transition roadmaps, and joint product licensing via FracQtion. Pricing is not publicly disclosed and follows a quote-based enterprise model. The company positions itself within Singapore's National Quantum Strategy (NQS) under the Research, Innovation and Enterprise 2025 plan, which earmarks ~SGD 300M for quantum research and ecosystem growth.
