    "abstract": "We report observations of entanglement of two remote atomic qubits, achieved\nby generating an entangled state of an atomic qubit and a single photon at Site\nA, transmitting the photon to Site B in an adjacent laboratory through an\noptical fiber, and converting the photon into an atomic qubit. Entanglement of\nthe two remote atomic qubits is inferred by performing, locally, quantum state\ntransfer of each of the atomic qubits onto a photonic qubit and subsequent\nmeasurement of polarization correlations in violation of the Bell inequality\n|S| \u003c2. We experimentally determine S =2.16 +/- 0.03. Entanglement of two\nremote atomic qubits, each qubit consisting of two independent spin wave\nexcitations, and reversible, coherent transfer of entanglement between matter\nand light, represent important advances in quantum information science.",
