Биоэлектроника — это междисциплинарная область, изучающая биологические материалы с точки зрения проводимости. Пространственная структура (или свертка) белка напрямую влияет на его физические и химические свойства, в том числе на проводимость. Моделирование пространственной структуры белка является вычислительно трудной задачей: число возможных степеней свободы делает моделирование экспоненциально сложным для классических вычислений из-за ограниченности ресурсов, а именно памяти и процессорного времени. Квантовые вычисления направлены на обработку многомерных данных, при которых потребность в вычислительных ресурсах (кубитах) растет логарифмически по отношению к размеру данных. Квантовые операторы, вентили, составляют квантовые программы, называемые контурами (или схемами).  В реальных квантовых компьютерах вентили являются неточными и дорогими в исполнении. Одним из способов повышения точности результата и снижения стоимости вычислений служит уменьшение количества квантовых вентилей. Данная работа описывает подход к уменьшению количества вентилей, состоящий из двух комбинируемых техник. Первая техника оптимизации основана на свойствах обратных и коммутирующих матриц. В данном случае оптимизированный контур при моделировании предсказывает такую же структуру белка, как и при моделировании исходным контуром, поскольку они математически эквивалентны. Вторая техника основана на исключении из квантового контура операторов с малоамплитудными параметрами. В этом случае оптимизированный контур рассчитывает приближенную структуру белка с погрешностью, зависящей от величины амплитуды параметров матриц. В ходе работы при моделировании части молекулы азурина удалось сократить глубину квантового контура с 631 до 629 вентилей первой техникой. Сокращение числа операторов первого метода совместно со вторым зависит от порогового значения, заданным вручную: для порогового значения 0.4 радиан глубина квантового контура составляет 314 вентиля.</p></abstract><trans-abstract xml:lang="en"><p>Computational material science aims to simulate substances to understand their physical properties. Bioelectronics is an interdisciplinary field that studies biological material from the conductivity point of view. In case of proteins, the folding is an important feature that directly influences physical and chemical properties. The folding modelling is a hard task. The enormous number of degrees of freedom makes modelling impossible for classical computation due to resource limits. Quantum computations aim to process multidimensional data with logarithmic growth of quantum bits. Quantum operators (gates) form quantum programs, known as circuits that process the input data. In real quantum computers, the gates are noisy and expensive to execute. Thus, it is essential to reduce the number of quantum gates both for the quality of the result and the cost of computations. This work describes an approach to decrease the number of quantum gates based on their mathematical property. The matrix properties form the first optimization technique. In this case, the optimized quantum circuit predicts precisely the same protein folding as the not optimized circuit predicts. This happens because both of the circuits are mathematically equivalent. The removal of weakly-parametrized gates forms the second optimization technique. In such case the optimized quantum circuit calculates the approximate protein folding. The error depends on parameter’s amplitude of the gates. The first technique allows to decrease the circuit depth from 631 to 629 gates while modelling the part of Azurin peptide. The second technique allows to decrease the depth to 314 gates with the threshold parameter value 0.4 radians.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>квантовые технологии</kwd><kwd>оптимизация</kwd><kwd>моделирование</kwd><kwd>биоэлектроника</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quantum technology</kwd><kwd>optimization</kwd><kwd>modelling</kwd><kwd>bioelectronics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zhang L., Lu J.R., Waigh T.A.
