Entanglement Detection with Variational Quantum Interference: Theory and Experiment
Rui Zhang, Zhenhuan Liu, Chendi Yang +7
Entanglement detection is a fundamental task in quantum information science, serving as a cornerstone for quantum benchmarking and foundational studies. With an increasing qubit nu…
Unconditional quantum teleportational advantage of single photons
Li-Chao Peng, Dian Wu, Xue-Mei Gu +10
Photon loss is the biggest enemy in quantum communications. Direct transmission typically results in a small fraction of photons surviving over long distances, hindering advanced a…
Experimental Quantum Channel Purification
Yue-Yang Fei, Zhenhuan Liu, Rui Zhang +7
Quantum networks, which integrate multiple quantum computers and the channels connecting them, are crucial for distributed quantum information processing but remain inherently susc…
Entanglement Superactivation in Multiphoton Distillation Networks
Rui Zhang, Yue-Yang Fei, Zhenhuan Liu +9
In quantum networks, after passing through noisy channels or information processing, residual states may lack sufficient entanglement for further tasks, yet they may retain hidden…
Robust quantum computational advantage with programmable 3050-photon Gaussian boson sampling
Hua-Liang Liu, Hao Su, Si-Qiu Gong +34
The creation of large-scale, high-fidelity quantum computers is not only a fundamental scientific endeavour in itself, but also provides increasingly robust proofs of quantum compu…
Error-mitigated inference of quantum network topology
Jun-Hao Wei, Xin-Yu Xu, Shu-Ming Hu +4
Paramount for performances of quantum network applications are the structure and quality of distributed entanglement. Here we propose a scalable and efficient approach to reveal th…
