Can quantum sensing improve magnetic navigation? Pentagon thinks one company is on the right track

Quantum devices that measure Earth's magnetic fields could help replace GPS—if researchers can figure out how to tell when such devices are working well, or even at all. A Pentagon contract suggests one company is solving that key problem.On Tuesday, SandboxAQ announced an agreement with the Defense Innovation Unit to join the Transition of Quantum Sensing program, or TQS, which allows the military to test the company’s AQNav software aboard a range of aircraft under a variety of con
