Nitride Global wins AFWERX contract for chip-scale quantum navigation sensor

Nitride Global has landed an AFWERX SBIR Phase I contract to prove out a centimeter-scale atom-chip sensor for navigation and remote sensing. The Wichita company says the work could help defense platforms operate without GPS and open commercial uses such as subsurface mapping.

Why it matters: - The contract targets a navigation problem that grows more urgent as GPS jamming and spoofing become more common in contested environments. - A deployable quantum sensor could improve positioning, navigation and timing for aircraft, drones, orbital systems, submerged platforms and autonomous ground vehicles. - The same sensor class could also support commercial work in resource exploration, infrastructure monitoring and subsurface mapping.

What happened: - Nitride Global said it won an AFWERX SBIR Phase I contract to support the Department of the Air Force. - The award funds a feasibility study for a centimeter-scale microwave atom chip quantum sensor for precision navigation and remote sensing gravimetry. - The company will evaluate an integrated Atom-Interferometer Microwave Atom Chip, or A-MAC, built on its aluminum oxynitride, or AlON, platform. - The Wichita, Kansas company said the effort is meant to address positioning, navigation and timing gaps in GPS-denied environments.

The details: - The A-MAC design is intended to consolidate distributed microwave hardware onto a single integrated board. - Nitride Global said its AlON material is a thin, conformal, high-isolation dielectric that allows microwave routing, coupling structures and trap geometry to sit on one stack. - The packaging approach is designed to move heat outward through metal rather than through a bulk ceramic substrate. - The target is a centimeter-scale architecture for size-, weight- and power-constrained platforms. - The Phase I team includes Dr. Seth Aubin, associate professor of physics at William & Mary, as a subcontractor and research partner. - Aubin’s lab has spent more than a decade developing microwave atom chip traps, the microwave AC Zeeman force for ultracold atoms and AC Zeeman potentials for atom interferometry. - The teams will model thermal behavior, microwave insertion loss, coupling and candidate trap geometries. - The Phase I work ends with a decision gate and a Phase II technical roadmap. - Nitride Global said the same AlON-on-copper stack is being industrialized for power modules, 2.5D/3D packaging, RF systems and optical systems. - The company said the platform has shown up to a 47% reduction in thermal resistance versus industry-standard materials and more than 10X in advanced packaging. - Nitride Global is also seeking engagement from aerospace and defense integrators to define form factor, environmental envelope and performance thresholds. - The company included more information on its website. - AFWERX also provided additional details about its mission and programs.

Between the lines: - The core challenge is not the sensing physics, but the packaging needed to make the physics fieldable. - Nitride Global is betting that its materials and thermal-management stack can shrink lab-scale quantum hardware into something that can fly. - The William & Mary partnership adds atomic-physics expertise to a materials and packaging effort, which raises the odds that the project can move from concept to a practical prototype.

What's next: - The Phase I effort will determine whether the integrated sensor is technically feasible. - If the study clears the decision gate, Nitride Global and its partners will move into a Phase II technical roadmap. - The company said integrators interested in compact quantum inertial sensing can help shape transition requirements.
