Entanglement-Based Distributed Quantum Sensing Enhanced by Quantum Relays
Yi Xia, Quntao Zhuang, William Clark, Zheshen Zhang · Conference on Lasers and Electro-Optics · 2019
We show that noiseless linear amplifiers can serve as quantum relays to overcome entanglement distribution loss for entangled quantum sensors to outperform sensors supplied with the optimum local quantum resources.
