Quantitative complementarity between local and nonlocal character of quantum states in a three-qubit system
Xinhua Peng, Jingfu Zhang, Jiangfeng Du +1
Local or nonlocal character of quantum states can be quantified and is subject to various bounds that can be formulated as complementarity relations. Here, we investigate the local…

Direct observation of quantum criticality in Ising spin chains
Jingfu Zhang, Fernando M. Cucchietti, C. M. Chandrashekar +6
We use NMR quantum simulators to study antiferromagnetic Ising spin chains undergoing quantum phase transitions. Taking advantage of the sensitivity of the systems near criticality…
