While their capability to detect modulated signals has\nbeen previously demonstrated, these studies have largely been limited to laboratory-generated signals tailored specifically for atomic detection. Here, we extend the practical applicability of Rydberg\nsensors by demonstrating the reception of real-world frequency-modulated (FM) audio transmissions\nusing a consumer-grade handheld two-way radio operating in the UHF band. Detection is based\non the AC Stark shift induced by the radio signal in a Rydberg atomic vapor, with demodulation\nperformed using an offset local oscillator and lock-in amplification. We successfully demodulate\nspeech signals and evaluate the audio spectral response and reception range. We show that all\nconsumer-accessible radio channels can be simultaneously detected, and demonstrate simultaneous\nreception of two neighboring channels with at least 53 dB of isolation. This work underscores the\npotential of Rydberg atom-based receivers for practical, real-world FM signal detection.", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/3947_README.txt", "mediaType": "text/plain", "title": "3947_README"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig1b.csv", "mediaType": "text/csv", "title": "Figure 1b"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig2c.csv", "mediaType": "text/csv", "title": "Figure 2c"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig3b.csv", "mediaType": "text/csv", "title": "Figure 3b"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig4.csv", "mediaType": "text/csv", "title": "Figure 4"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig5.csv", "mediaType": "text/csv", "title": "Figure 5"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig6.csv", "mediaType": "text/csv", "title": "Figure 6"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig7b.csv", "mediaType": "text/csv", "title": "Figure 7b"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig8.csv", "mediaType": "text/csv", "title": "Figure 8"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3947/Fig9.csv", "mediaType": "text/csv", "title": "Figure 9"}], "identifier": "ark:/88434/mds2-3947", "issued": "2025-09-15", "keyword": ["Rydberg atoms", "atomic physics", "electric field", "fields strength", "receivers", "volts/meter"], "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2025-07-29 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["https://doi.org/10.1103/jlrg-6889"], "theme": ["Advanced Communications:Quantum communications", "Advanced Communications:Wireless (RF)", "Metrology:Electrical/electromagnetic metrology", "Physics:Atomic, molecular, and quantum", "Physics:Optical physics", "Physics:Spectroscopy"], "title": "Data associated with \"Rydberg atom reception of a handheld UHF frequency-modulated two-way radio\""}
