University of Warsaw researchers demonstrated a microwave measurement that captured three times more information about field strength than a corresponding measurement without interactions between atoms. The laboratory result, published in Nature Communications, used cold Rydberg atoms, whose excited electrons make them sensitive to electric fields.

Preparing interactions between the atoms changed their state so that subsequent detection losses destroyed less information. The comparison measured Fisher information, which describes how precisely a parameter can be estimated; it does not mean sensitivity itself tripled. Losses still reduced sensitivity.
