Implementation of a 46-node quantum metropolitan area network
Teng-Yun Chen, Xiao Jiang, Shi-Biao Tang +22
Quantum key distribution (QKD) enables secure key exchanges between two remote users. The ultimate goal of secure communication is to establish a global quantum network. The existi…
Performance Optimization on Practical Quantum Random Number Generators: Modification on Min-entropy Evaluation and Acceleration on Post Processing
Zehao Zhao, Xiongfeng Ma, Hongyi Zhou
Quantum random number generation is a technique to generate random numbers by extracting randomness from specific quantum processes. As for practical random number generators, they…
Quantum Coherence Witness with Untrusted Measurement Devices
You-Qi Nie, Hongyi Zhou, Jian-Yu Guan +4
Coherence is a fundamental resource in quantum information processing, which can be certified by a coherence witness. Due to the imperfection of measurement devices, a conventional…
Randomness expansion secured by quantum contextuality
Mark Um, Qi Zhao, Junhua Zhang +6
The output randomness from a random number generator can be certified by observing the violation of quantum contextuality inequalities based on the Kochen-Specker theorem. Contextu…
Unification of quantum resources in distributed scenarios
Hongyi Zhou, Xiao Yuan, Xiongfeng Ma
Quantum resources, such as coherence, discord, and entanglement, play as a key role for demonstrating advantage in many computation and communication tasks. In order to find the na…
Randomness quantification of coherent detection
Hongyi Zhou, Pei Zeng, Mohsen Razavi +1
Continuous-variable quantum cryptographic systems, including random number generation and key distribution, are often based on coherent detection. The essence of the security analy…
