As militaries contend with increasingly jammed and contested airwaves, Infleqtion has unveiled an atom-based radio-frequency (RF) sensing system aimed at overcoming the limits of conventional technologies.
Called Quantum Spectrum, the system is designed to detect, classify, and authenticate RF signals in contested electromagnetic environments.
It leverages Rydberg atoms to capture continuous frequencies across the radio spectrum, from hertz to terahertz, through a single aperture.
This approach enables broader spectrum awareness, earlier signal detection, and more consistent performance in environments where traditional systems are often strained.
“We’ve been developing atom-based RF sensing for nearly a decade, and the milestones we’ve reached make clear that now is the time to accelerate with greater corporate focus,” said Matt Kinsella, chief executive officer of Infleqtion.
“We’re building prototypes, running field trials, and hardening these systems for real-world deployment. Quantum Spectrum is a new category we are both defining and leading.”
From Lab to Deployment
The system is currently in the development and field-testing phase, with a roadmap aimed at transitioning prototypes into a scalable family of receivers.
It is also being evaluated through defense initiatives across the US, the UK, and Australia.
Under the Robust, Integrated Quantum Electromagnetic Receiver (RIQER) program, the company is working with the US Army Research Laboratory to develop a mobile variant of the system.
This version is intended to serve as a testbed for US Army mission requirements, including positioning, navigation, and timing, as well as spectrum monitoring in GPS-denied environments.
Through operational testing and integration with army test infrastructure, the RIQER effort is expected to bring quantum RF sensing closer to field deployment.
