Creating and controlling global Greenberger-Horne-Zeilinger entanglement on quantum processors

Kavli Affiliate: Biao Huang | First 5 Authors: Zehang Bao, Shibo Xu, Zixuan Song, Ke Wang, Liang Xiang | Summary: Greenberger-Horne-Zeilinger (GHZ) states, also known as two-component Schr"{o}dinger cats, play vital roles in the foundation of quantum physics and, more attractively, in future quantum technologies such as fault-tolerant quantum computation. Enlargement in size and coherent […]
