Original Abstract Submitted

a quantum repeater forwards quantum information along with measurement results, enabling a destination endpoint to recover the original quantum information. the quantum repeater receives an input graph state encoding at least one logical qubit from a source endpoint. the quantum repeater generates a first multi-photonic graph state and entangles the input graph state with the first graph state. the quantum repeater forwards the quantum information by providing at least a portion of the first graph state to a subsequent quantum repeater or to the destination endpoint. the quantum repeater also measures the input graph state and provides the measurement results to the destination endpoint, enabling the destination endpoint to recover the at least one logical qubit from the source endpoint.
