Abstract:
Quantum computers, which harness the principles of quantum physics, are advancing at an unprecedented pace. These systems represent a transformative leap in computing, enabling the solution of complex and challenging problems that lie beyond the reach of classical computers. In recent years, significant progress has been made across the entire quantum computer stack, from hardware and software to system integration, interaction with classical computers, and practical applications in research and industry. This presentation briefly explains the core concepts of quantum computing, discusses the current state of the field, and explains the prerequisites for developing a robust tool for solving real-world problems. In order to increase performance—number of qubits, quality, and speed of the system—as quickly as possible, improvements are needed in all areas. A modular architecture combined with an efficient error correction algorithm will enable the construction of a highly scalable, fault-tolerant quantum computer with 200 logical qubits by 2029, capable of performing 100 million quantum operations. An overview of the challenges, recent advances in development, and the technology roadmap will be discussed.
