'quantum-based atom interferometers unjammable/ extremely precise motion/ position measure, but use large, power-hungry laser setups limiting deployment outside labs, overcome confining within tightly guided optical structures/ integrated photonic circuits... significantly lowers power consumption/ physical footprint, enhances vibration/ environmental noise resistance... resilient, high-accuracy autonomous navigation in GPS-denied environments like jammed military settings, underwater, underground"
