The new-generation QPU C Series superconducting quantum chips adopt an enhanced 2D lattice topology, greatly improving qubit connectivity and scalability. The architecture supports high-density integration of up to 103 superconducting qubits and provides native support for quantum error correction, enabling surface-code with code distance up to d = 7. This advancement establishes a robust physical foundation for conducting multi-level quantum error correction experiments and building fault-tolerant quantum computing architectures in future large-scale quantum systems.Learn More >
