Experimental Device-Independent Tests of Classical and Quantum Entropy
Feng Zhu, Wei Zhang, Sijing Chen +3
In this paper, we report an experiment about the device-independent tests of classical and quantum entropy based on a recent proposal [Phys. Rev. Lett. 115, 110501 (2015)], in whic…
Experimental Quantum Digital Signature over 102 km
Hua-Lei Yin, Yao Fu, Hui Liu +10
Quantum digital signature (QDS) is an approach to guarantee the nonrepudiation, unforgeability and transferability of a signature with the information-theoretical security. All pre…
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…
Measurement device independent quantum key distribution over 404 km optical fibre
Hua-Lei Yin, Teng-Yun Chen, Zong-Wen Yu +16
Quantum key distribution (QKD) can provide unconditional secure communication between two distant parties. Although the significance of QKD is undisputed, its feasibility has been…
Experimental quantum data locking
Yang Liu, Zhu Cao, Cheng Wu +13
Classical correlation can be locked via quantum means--quantum data locking. With a short secret key, one can lock an exponentially large amount of information, in order to make it…
Scalable boson sampling with a single-photon device
Yu He, Zu-En Su, He-Liang Huang +13
Boson sampling is a problem intractable for classical computers, but can be naturally solved on a specialized photonic quantum simulator which requires less resources than building…
