Google has announced a breakthrough in quantum computing with its new ‘Willow’ chip, solving a problem in just five minutes that would take classical computers an unimaginable length of time. This marks a major milestone in the race for quantum supremacy, with potential applications in fields like medicine, AI, and battery technology. Willow, developed at Google’s Santa Barbara lab, features 105 qubits – the building blocks of quantum computers – which are highly sensitive and prone to errors. To address this, Google’s team implemented advanced quantum error-correction, allowing error rates to decrease as more qubits are added. The findings, published in Nature, demonstrate real-time error correction, bringing practical quantum computing closer to reality. While the solved problem has no direct commercial use, this advancement highlights the promise of quantum systems to tackle challenges far beyond the capabilities of today’s technology.
