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. https://research-explorer.ista.ac.at/download/22637/22640/2026_PhysicalReviewX_AndresJuanes.pdf application/pdfno American Physical Society2026 eng 2160-330810.1103/r4jt-j39w 163 https://ista.ac.at/en/news/quantum-bath-syncs-distant-qubits/ Andres Juanes, Alejandro, et al. “Distributing Stationary Qubit Entanglement through a Nonlocal Squeezed Reservoir.” <i>Physical Review X</i>, vol. 16, no. 3, 031005, American Physical Society, 2026, doi:<a href="https://doi.org/10.1103/r4jt-j39w">10.1103/r4jt-j39w</a>.
