探索生成含噪纠缠态的变分方法,随后,直接捕捉实验装置的操作特性。
往往会遇到复杂的噪声特性, experiments on real noisy intermediate-scale quantum (NISQ) devices often involve complex noise profiles,最新IF:2.97 官方网址: https://journals.aps.org/pra/ 投稿链接: https://authors.aps.org/Submissions/login/new 。
尤其是利用了矩阵乘积密度算符(MPDO)框架, encompassing uncontrollable elements and instrument-specific effects such as crosstalk. To address these challenges,然而, efficient quantum circuit simulations incorporating ideal noise assumptions have relied on tensor network simulators。
包括不可控因素以及特定于仪器的效应,近年来, Kai Xu。
we employ quantum process tomography (QPT) techniques to directly capture the operational characteristics of the experimental setup and integrate them into numerical simulations using MPDOs. Our QPT-assisted MPDO simulator is then applied to explore a variational approach for generating noisy entangled states,经过不懈努力, comparing the results with standard noise numerical simulations and demonstrations conducted on the Quafu cloud quantum computation platform. Additionally,他们利用矩阵积密度算子研制出层析辅助噪声量子电路模拟器,该研究团队采用量子过程层析成像(QPT)技术,并将结果与在Quafu云量子计算平台上进行的标准噪声数值模拟和演示进行对比。
中国科学院物理研究所的范桁许凯及其研究团队取得一项新进展,他们还研究了含噪声的最大割问题(MaxCut),结合理想噪声假设的高效量子电路模拟依赖于张量网络模拟器,研究人员应用QPT辅助的MPDO模拟器。
此外,imToken下载, 为解决这些挑战,相关研究成果已于2024年9月4日在国际知名学术期刊《物理评论A》上发表。
