• Infleqtion on May 13, 2026 introduced “Quantum Spectrum,” an atom-based RF sensing platform it positioned as a new category within quantum sensing.
• Platform uses Rydberg atoms as sensing medium, aiming to replace conventional RF front ends with a single-aperture receiver that tunes continuously from hertz to terahertz for broader spectrum coverage.
• Development is backed by active defense contracts in U.S., U.K., Australia, with work focused on prototypes, field trials, ruggedization, and a productized receiver family.
• U.S. program with U.S. Army DEVCOM ARL under RIQER targets a transportable quantum RF demonstration system for PNT, spectrum monitoring, and operation in jammed or GPS-denied environments.
• U.K. QuDiFi program targets deployable direction finding using multiple sensor heads; Australia QOBRA effort targets a transportable receiver optimized with machine learning to improve sensitivity and instantaneous bandwidth.
