Improved key rate bounds for practical decoy-state quantum key distribution systems
Zhen Zhang, Qi Zhao, Mohsen Razavi +1
The decoy-state scheme is the most widely implemented quantum key distribution protocol in practice. In order to account for the finite-size key effects on the achievable secret ke…
Efficient measurement-device-independent detection of multipartite entanglement structure
Qi Zhao, Xiao Yuan, Xiongfeng Ma
Witnessing entanglement is crucial in quantum information processing. With properly preparing ancillary states, it has been shown previously that genuine entanglement can be witnes…
Entanglement Swapping with Independent Sources over an Optical Fibre Network
Qi-Chao Sun, Ya-Li Mao, Yang-Fan Jiang +14
Teleportation of an entangled state, known as entanglement swapping, plays an essential role in quantum communication and network.Here we report a field-test entanglement swapping…
Quantum Coherence and Intrinsic Randomness
Xiao Yuan, Qi Zhao, Davide Girolami +1
The peculiar uncertainty or randomness of quantum measurements stems from coherence, whose information-theoretic characterization is currently under investigation. Under the resour…
