Physivitis Ltd

Physivitis is a UK deep-tech company that turns frontier physics and AI into protected, commercial-ready IP. We work across the full quantum-AI-classical stack rather than a single layer, with a portfolio spanning quantum sensing and detection, post-quantum security, AI assurance, and quantum hardware.

The business runs on two complementary channels: IP licensing for hardware-dependent innovations, and direct software products delivered through subscription portals. The company holds twelve UK patent filings across these domains. Three products are already live in market, including USMC, a board-ready tool that turns an organisation's post-quantum security exposure into a single, defensible risk score, with paying enterprise customers at pre-seed. One innovation is open-sourced, and the company is an approved member of NVIDIA Inception.

For the quantum community, our most relevant work sits in superconducting photodetection, quantum-detection optimisation, and a cryogenic-module innovation aimed at the cooling overhead that constrains quantum scaling. These are validated in simulation and ready for real-world testing, so we are actively seeking measurement and validation partners, detector groups, and instrumentation collaborators, alongside licensees for the hardware-dependent IP.
