%X Quantum communication relies on the efficient generation of entanglement between remote quantum nodes, as entanglement is required to achieve and verify secure communications1. Remote entanglement has been realized using a number of different probabilistic schemes2,3, but deterministic remote entanglement has only been demonstrated recently, using a variety of superconducting circuit approaches4,5,6. However, the deterministic violation of a Bell inequality7, a strong measure of quantum correlation, has not been demonstrated so far in a superconducting quantum communication architecture, in part because achieving sufficiently strong correlation requires fast and accurate control of the emission and capture of the entangling photons. Here, we present a simple and robust architecture for achieving this benchmark result in a superconducting system
