Existing approaches rely on deterministic state transfer, or probabilistic protocols that require active control or measurements and postselection. Here, we demonstrate a fundamentally different, fully autonomous process, where two remote qubits are entangled through their coupling to a quantum-correlated photonic reservoir. In our experiment, a Josephson parametric converter produces a Gaussian, continuous-variable entangled state of propagating microwave fields that drives two spatially separated superconducting transmon qubits into a stationary, discrete-variable entangled state. We also show how qubit tomography unlocks a direct and sensitive verification of two-mode squeezing in the microwave domain. These results establish networks of qubits interfaced with distributed continuous-variable entangled states as a powerful platform for foundational studies and quantum-technology applications.","lang":"eng"}],"issue":"3","project":[{"name":"QUANTUM INFORMATION SYSTEMS BEYOND CLASSICAL CAPABILITIES / P5- Integration of Superconducting Quantum Circuits","_id":"bdb108fd-d553-11ed-ba76-83dc74a9864f","grant_number":"F07105"},{"_id":"bdadfa0d-d553-11ed-ba76-fb85edbd456a","name":"Cavity Quantum Electro Optics: Microwave photonics with nonclassical states","grant_number":"101089099"}],"DOAJ_listed":"1","status":"public","corr_author":"1","PlanS_conform":"1","intvolume":"        16","ddc":["530"],"date_published":"2026-07-13T00:00:00Z","scopus_import":"1","supplementarymaterial":"yes","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_created":"2026-08-03T13:19:31Z","das_tickbox":"1","file_date_updated":"2026-08-04T05:40:41Z","article_processing_charge":"Yes","file":[{"date_updated":"2026-08-04T05:40:41Z","date_created":"2026-08-04T05:40:41Z","file_size":5301241,"creator":"dernst","file_name":"2026_PhysicalReviewX_AndresJuanes.pdf","success":1,"relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_id":"22640","checksum":"2bab109f975545d096c21dd72c738b6e"}],"publisher":"American Physical Society","oa":1,"quality_controlled":"1"}
