A Chinese group led by China Telecom Quantum Computing Group has unveiled Xiaohong-504, a 504-qubit quantum computing chip, and Tianyan-504 superconducting quantum computer. The achievement can be considered a groundbreaking milestone in China, reports Interesting Engineering.
The heart of the Tianyan-504 is Xiaohong, a superconducting chip with 504 qubits, which is a record for China. The report says that Xiaohong's performance metrics, such as qubit lifetime, gate fidelity, and quantum circuit depth, are designed to rival international platforms like those offered by IBM. However, the primary focus of the processor and the quantum computer is on advancing the infrastructure for large-scale quantum systems rather than solely pursuing computing performance or quantum supremacy.
