Researchers at NIST have demonstrated a new quantum-based communication method using low-frequency magnetic radio signals that could enable reliable communication and mapping in challenging environments like underwater, underground, and indoors where GPS and conventional radio signals fail. The technology, which relies on quantum sensors using rubidium atoms, offers higher sensitivity and bandwidth compared to classical methods, potentially enabling communication and location tracking in environments where traditional methods are ineffective. The NIST team is working on developing improved transmitters and noise suppression techniques to further enhance the technology’s performance and practicality.
