ColdQuanta, a Colorado-based quantum hardware company, has been awarded a contract from the Defense Advanced Research Projects Agency (DARPA) to develop a Rydberg atom-based radio frequency (RF) sensor system. The contract involves other parties such as BAE Systems, Teledyne Scientific and Imaging, and the University of Oklahoma to collectively work toward the goal.
The value of the contract has not been disclosed. This is the second DARPA contract for the company following the first one in April 2020 with a value of USD 7.4 million.
The contract has been awarded under DARPA’s Quantum Apertures program which focuses on developing improved RF sensors for national security purposes. The contract aims to produce a system that has a broad RF spectral range—10 megahertz to 40 gigahertz— and does not require an extensive antenna. The system will also come with a small sensor head size, making the system portable while maintaining its sensitivity and capabilities.
The prototype of the system is expected to be available in 1.5 years and the portable system in 2.5 years. The system’s applications include military communications, radar, and electronic warfare, and other defense activities. The company is also exploring the possibilities of using quantum RF sensing receivers in 5G, 6G, and low orbit satellite networks.
