Two tasks, boson sampling and random quantum circuit sampling, have experimentally exhibited quantum advantages on photonic and superconducting platforms respectively. Classical benchmarking is essential, yet challenging, because these tasks are intractable for classical computers. This study reviews models, algorithms and large-scale simulations of these two sampling tasks.

The development of this field is traced, from earliest classical views to the state-of-the-art picture based on methods of quantum field theory. A quasi-local view point, characterizing “pure” Mott physics, throughout this article is focused on. Following an extensive discussion on Mott transitions in one- and multi-orbital Hubbard models, progress is reviewed in first-principles correlation-based approaches in achieving a quantitative description of insulator-metal transitions in two celebrated Mott materials. Building thereupon, success of such approaches in providing microscopic justification for the famed Mott criterion, as well as in the attempts to model emerging devices is reviewed briefly. The study is concluded with a discussion of a class of Mott insulators modeled by the Kugel-Khomskii model, and discuss how progress in the understanding of novel quantum liquid-crystal-like order provides an attractive opportunity to gain insight into topologically ordered states and topological-to-trivial phase transitions for certain quantum spin models in terms of a dual description in terms of Landau-like symmetry breaking.</p>","PeriodicalId":72073,"journal":{"name":"Advanced quantum technologies","volume":"7 12","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional methods, which rely on conducting time-intensive Hanbury Brown-Twiss (HBT) experiments to acquire the 2nd-order correlation function of photon statistics, are not efficient. This study presents a pioneering solution that employs Deep Convolutional Neural Networks (CNNs) to classify single-photon emitters in confocal fluorescence microscope images, thereby bypassing the need for laborious HBT experiments. Focusing on the nitrogen-vacancy centers in diamond, the model is trained using fluorescence images of emitters that have been previously classified through HBT experiments. Applied to unclassified fluorescence images, the model achieves up to 98% accuracy in classification, substantially accelerating the identification process. This advancement not only makes the classification workflow more efficient but also promises wider applicability across various color centers and isolated atomic systems that necessitate imaging for isolation verification.
