Entanglement is a unique resource for quantum-enhanced applications. Whenemployed in sensing, shared entanglement between distributed quantum sensorsenables a substantial gain in the measurement sensitivity in estimating globalparameters of the quantum sensor network. Loss incurred in the distribution ofentanglement, however, quickly dissipates the measurement-sensitivity advantageenjoyed by the entangled quantum sensors over sensors supplied with localquantum resources. Here, we present a viable approach to overcome theentanglement-distribution loss and show that the measurement sensitivityenabled by entangled quantum sensors beat that afforded by the optimum localresource. Our approach relies on noiseless linear amplifiers (NLAs) to serve asquantum repeaters. We show that unlike the outstanding challenge of buildingquantum repeaters to suppress the repeaterless bound for quantum keydistribution, NLA-based quantum repeaters for distributed quantum sensing arerealizable by available technology. As such, distributed quantum sensing wouldbecome the first application instance that benefits from quantum repeaters.
