摘要
Whether in medical or security applications, magnetic resonance spectroscopy is very useful for detecting faint signals from target compounds. However, interference (from $e.g.$ a local radio station) can be a problem. The authors devise optical atomic-gas detectors that work in unshielded environments, and without cryogenic cooling---important advantages for real-world use. These sensitive, compact systems offer baseline noise at the quantum limit.
