Englund"],"abstract":"Semiconductor single-photon detectors cannot be straightforwardly adapted for the microwave regime, primarily because microwave photons carry far less energy and thus require cryogenic temperatures and specialized architectures. Here, we propose a hybrid spin-optomechanical interface to detect single microwave photons where the microwave photons are coupled to a phononic resonator via piezoelectric actuation. This phononic cavity also acts as a photonic cavity with either a single embedded Silicon-Vacancy (SiV) center in diamond or an ensemble of these centers, bridging optical single-photon detection protocols into the microwave domain. We model the detection process as a communication channel whose capacity is quantified by the mutual information \\(I(A;B)\\) between the true photon occupancy (A) and the detector outcome (B). Depending on experimentally achievable parameters, simulations predict \\(I(A;B)\\) in the range \\(0.57\\,\\ln(2)\\) to \\(0.67\\,\\ln(2)\\), corresponding to true-positive (detection) probabilities above 90\\% and false-positive (dark count) probabilities below 10\\% per detection interval. These results suggest a viable path to low-noise, high-efficiency single-photon detection at microwave frequencies.","url_abs":"https://arxiv.org/abs/2401.10455v2","url_pdf":"https://arxiv.org/pdf/2401.10455v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"microwave-single-photon-detection-using-a","repo_url":"https://github.com/panand2257/single-photon-detection","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
