Quantum Showdown: China’s Zuchongzhi-3
China’s Zuchongzhi-3 quantum computer and Google’s Willow processor represent two contrasting approaches in the race for quantum supremacy. Both 105-qubit superconducting systems push computational boundaries but prioritize different technical milestones. Zuchongzhi-3, developed by Chinese researchers, demonstrates remarkable raw computational power. In a demanding random circuit sampling task, it processed one million samples using 83 qubits over 32 cycles in just a few hundred seconds—a feat that would take the world’s fastest classical supercomputer billions of years to replicate. This achievement highlights China’s rapid progress in scaling up quantum hardware and achieving unprecedented quantum speedup. ...
