Abstract: Possessing high-speed computing and error-correction capabilities, yet still far from commercial use, Google has unveiled its supercomputer ‘Quantum Chip’. On the outside, it resembles a piece of black chocolate, but the ‘small stature’ of this thin slice contains a ‘great power’ that should not be underestimated. It is Google’s latest quantum chip ‘Willow’, announced on the 9th in the United States. According to Google, ‘Willow’ has achieved two breakthroughs in the field of quantum computing. First, it significantly reduces errors when using more qubits, solving a quantum error-correction challenge that has persisted for about 30 years. Second, it completes tasks that would take today’s fastest supercomputers 10^25 years to finish in less than 5 minutes.
