ONE QUANTUM ANTENNA CAN HEAR THE ENTIRE RADIO SPECTRUM. Every antenna in the world is built for one slice of radio. The physics forces it, an antenna has to be roughly the size of the wavelength it's catching, so a low frequency HF antenna is tens of meters long and a Ku-band dish is a small plate. A warship or an aircraft carries dozens, one per band, and every one is a visible, jammable piece of metal, but this is changing. Infleqtion's Quantum Spectrum does it with a cloud of atoms. Excite cesium atoms into a Rydberg state, where the outer electron orbits far from the nucleus, and the atom becomes exquisitely sensitive to electric fields. Shine a laser through the cloud and you can read any radio signal passing by. The current generation covers 1 MHz to 12 GHz continuously in a single aperture, HF through Ku band, with a roadmap that stretches toward terahertz. It fits in a 4U rack unit, down from 9U a generation ago, with chip scale packaging on the roadmap. Why militaries are paying for it: It listens without transmitting, so it can't be detected the way a radar can. It's hard to jam, because the atoms aren't tuned to one frequency to overload and one unit monitors the whole spectrum at once, which is the core job of signals intelligence and electronic warfare. Three countries have already bought in. The U.S. Army, through its research lab, for transportable quantum RF systems. The U.K., for a multi-sensor direction finding program. Australia's defense science group, for a broadband receiver. Integration partners include L3Harris, SAIC, and Dell Federal. $INFQ $IONQ $QNT
THE MILITARY IS GOING QUANTUM. THESE 7 COMPANIES ARE IN POSITION TO WIN. Farseer is DIU's $200 million program to put quantum sensors into the military within months with magnetometers, gravity gradiometers, tactical clocks, and components. Proposals closed in July.
