ROSHARON, TX / ACCESS Newswire / November 17, 2025 / The world is bracing for the inevitable impact of quantum computing on cybersecurity and Signal Advance Inc. ( SIGL ) has taken a pivotal step forward with its Analog Guard® technology - a physics-based encryption platform developed to outpace quantum threats.

Traditional encryption relies on mathematical puzzles that today's supercomputers can't crack quickly - but quantum computers will, in seconds.

Analog Guard® was built beyond quantum's reach. Not retrofitted. Not patched. Designed from day one using physics, not math. No computational complexity to exploit; no algorithms for quantum to unravel. It strips attackers of their leverage - and sets the new gold standard in a world under an advanced persistent cybersecurity threat.

"Quantum computing will redefine the limits of computation but it can't rewrite the laws of physics," said Dr. Chris Hymel, Ph.D., President & CEO of Signal Advance ( SIGL ). "Analog Guard® isn't just a game-changer - it's a seminal shift- moving encryption from increasing vulnerable math to robust physics. It's uniquely engineered for the quantum era."

Earlier this year, Signal Advance ( SIGL )® announced AI-resistance test results indicating that even advanced neural networks called CNNs (Convolutional Neural Networks - the same tech behind ChatGPT and facial recognition) - performed no better than a coin flip when analyzing Analog Guard®-encrypted files. In other words, in an environment aptly named for "deep learning", AI could learn nothing - confirming Analog Guard's® strength lies in its pattern-less, physics-based design, making it inherently resistant to both AI-driven and quantum-driven cryptanalysis.

Global awareness of quantum risk is rising rapidly. Elon Musk is raising new questions about Bitcoin's long-term safety in the face of rapid advances in quantum computing. (August 3, 2025, Bitcoinist.com) a concern highlighting how quantum breakthroughs may soon undermine digital cryptography itself

This matters because global cybercrime costs are now projected to exceed US $19.7 trillion by 2030 (Global Cybercrime Report 2025, December 3, 2024, proxyrack.com). The need for new forms of security has never been greater.

Analog Guard® introduces a fresh, hardware-native alternative - one that's not bound by algorithms and is compatible with both existing digital networks and future quantum-safe systems. It isn't just quantum-ready - it's quantum safe by design, hardware-native, and scalable.

Next Steps

With quantum computing test protocols finalized, Signal Advance ( SIGL )® will begin circuit simulation Quantum-Resilience Validation in Q1 2026; hardware testing will follow in a subsequent phase. The Company is also exploring collaborations to accelerate deployment across defense, finance, telecommunications, and industrial-control markets.
