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…
Homogeneous fermionic Hubbard gases in a flat-top optical lattice
Yu-Xuan Wang, Hou-Ji Shao, Yan-Song Zhu +6
Fermionic atoms in a large-scale, homogeneous optical lattice provide an ideal quantum simulator for investigating the fermionic Hubbard model, yet achieving this remains challengi…
Feshbach spectroscopy of ultracold mixtures of and atoms
Ke Xie, Xi Li, Yu-Yang Zhou +7
We report on the observation of Feshbach resonances in ultracold - mixtures, where atoms are respectively prepared in their three…
