New system detects faint communications signals using the principles of quantum physics – Phys.org

Researchers at the National Institute of Standards and Technology (NIST) have devised and demonstrated a system that could dramatically increase the performance of communications networks while enabling record-low error rates in detecting even the faintest of signals, potentially decreasing the total amount of energy required for state-of-the-art networks by a factor of 10 to 100.
The proof-of-principle system consists of a novel receiver and corresponding signal-processing technique that, unli…
