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…
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…
Virtual Channel Purification
Zhenhuan Liu, Xingjian Zhang, Yue-Yang Fei +1
Quantum error mitigation is a key approach for extracting target state properties on state-of-the-art noisy machines and early fault-tolerant devices. Using the ideas from flag fau…
