This work presents a brief overview of the current state of quantum computing. In recent years, this field of research has seen rapid progress, primarily in the development of experimental methods for controlling the states of multiparticle quantum systems. At the same time, the question of the practical applications of quantum computing remains open. The most promising areas, where such applications may emerge in the coming years, include solving problems in quantum chemistry, materials science, and various optimization problems. Current experimental work on the implementation of various quantum algorithms using intermediate-scale quantum processors with tens and hundreds of qubits—two-level quantum systems that are the fundamental logical elements of a quantum computer—has generated considerable interest in the scientific community. This is clearly demonstrated by the results of a bibliometric analysis conducted using Google Scholar and ChatGPT.
The experimental implementation of quantum computing is currently characterized by competition among several physical platforms, with the superconducting platform leading the way, a feat recognized by the 2025 Nobel Prize in Physics. At the same time, alternative platforms—photons, ions, and neutral atoms—offer a number of potential advantages. The most significant development in experimental quantum computing in future years is quantum error correction, which should increase the depth of quantum algorithms and enable the implementation of the most complex universal quantum algorithms. The basic principles of quantum error correction and the implementation of a surface code that best suits the architecture of modern quantum processors are presented in the article.
Based on existing superconducting quantum processors, cloud access has been implemented, allowing researchers to conduct both numerical simulations and experiments on the implementation of quantum computing. The IBM Qiskit library, which has become the de facto standard, is widely used for this purpose. As an example, the paper presents a demonstration of elements of a surface code for quantum error correction, implemented using large language models.
