The computational resource required for the optimization is an essential consideration in order to scale toward quantum control of larger registers. Here, we propose and demonstrate the use of a machine learning method, specifically the recommender system (RS), to deal with the challenge of enhancing computational efficiency. Given a sparse database of a set of products and their customer ratings, RS is used to efficiently predict unknown ratings. In the quantum control problem, each iteration of a numerical optimization algorithm typically involves evaluating a large number of parameters, such as gradients or fidelities, which can be tabulated as a rating matrix. We establish that RS can rapidly and accurately predict elements of such a sparse rating matrix. Using this approach, we expedite a gradient ascent based quantum control optimization, namely GRAPE, and demonstrate the faster construction of two-qubit CNOT gate in registers with up to 8 qubits. We also describe and implement the enhancement of the computational speed of a hybrid algorithm involving simulated annealing as well as gradient ascent. Moreover, the faster construction of three-qubit Toffoli gates further confirmed the applicability of RS in larger registers.</p></div>","PeriodicalId":36067,"journal":{"name":"Physics Open","volume":"14 ","pages":"Article 100127"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49760708","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}

In this study, a series of Exfoliated Graphite (EG) in combination with U-type barium hexaferrite based epoxy composites was fabricated with varying weight percentages (0.25, 0.50, 0.75 and 1.00 wt%) of EG and fixed wt.% (60 wt%) of U-type hexaferrite through wet mixing and compression moulding technique. Here, Raman spectra shows the EG to be defect-free characteristics. Subsequently, prepared composites were measured for microstructure and electromagnetic (EM) properties in 8.2–12.4 GHz frequency range (X-band). Further, complex permittivity (ε<sub>r</sub> = <em>ε</em>′−jε″) and complex permeability (μ<sub>r</sub> = μ′−jμ″) of the designed composites were measured using Vector Network Analyzer (VNA). Designed EG/hexaferrite-epoxy composite shows maximum real permittivity and permeability values (<em>ε</em>′ = 18.90 and μ′ = 0.91) for 3.3 mm thickness with minimum reflection loss −8.43 dB with 0.75 wt % EG filled (Sample-3)in X-band. While, it can withstand the different mechanical forces and shown the better absorption mechanism.EG plays important role due to their unique properties with optimize loading percentages in ferrite-epoxy composites. It may be concluded that, optimized EG/hexaferrite based composites determine as good microwave absorber in 8.2–12.4 GHz frequency ranges. Consequently, the prepared structural composites can be used to design the microwave absorbers and electromagnetic interference (EMI) shields for stealth applications.</p></div>","PeriodicalId":36067,"journal":{"name":"Physics Open","volume":"14 ","pages":"Article 100138"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49756505","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}
