Chinese researchers have made a breakthrough in quantum technology by introducing Tianyan-504 — a quantum computer with a superconducting chip, a record for the country Xiaohong for 504 qubits. The system demonstrates competitive characteristics, such as qubit lifetime and calculation accuracy, that put it on par with leading international developments, including IBM platforms.
This computer is a joint achievement of China Telecom's Quantum Group (CTQG), the Chinese Academy of Sciences, and QuantumCTek, a company specializing in quantum technologies. Its creation opens up new opportunities for research in cryptography, material modeling and solving optimization problems, where quantum computing provides a significant advantage.
Tianyan-504 will be the basis of the cloud platform Tianyan, launched in November 2023. This platform has already attracted more than 12 million users from more than 50 countries, providing global access to quantum computing. Xiaohong's developed chip will be tested on kiloqubit measurement and control systems, which are key performance components of quantum computers.
China is consistently establishing leadership in the quantum industry, using both photonic (Jiuzhang 2.0 processor) and superconducting (Zuchongzhi 2.1) technologies. Achieving a quantum advantage in both approaches demonstrates the country's scientific and technological strength. In addition, China's Tianhe supercomputer continues to lead the field of artificial intelligence, contributing to progress in materials science, meteorology and other scientific fields.
- China has created the most powerful ion quantum computer: Chinese scientists have developed an ion quantum computer that exhibits the highest power among analogues, underscoring the country's leadership in the field of quantum technology.
- The smallest quantum computer is presented: Researchers at National Tsinghua University in Taiwan have created a box-sized single-photon quantum computer capable of performing complex calculations such as Shor's algorithm, demonstrating the potential for miniaturization of quantum devices.
