In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Thus, Google claimed to have achieved quantum supremacy. To estimate the time that would be taken by a classical supercomputer, Google ran portions of the quantum circuit simulation on the Summit, one of the most powerful classical computers in the world.[3][4][5][6][7][8] Later, IBM made a counter-argument, claiming that the task would only take 2.5 days on a classical system like Summit.[9][10] If Google's claims are upheld, then it would represent an exponential leap in computing power.[11][12][13]

Today I’m delighted to announce Willow, our latest quantum chip. Willow has state-of-the-art performance across a number of metrics, enabling two major achievements.

When I founded Google Quantum AI in 2012, the vision was to build a useful, large-scale quantum computer that could
harness quantum mechanics — the “operating system” of nature to the extent we know it today —

- The first is that Willow can reduce errors exponentially as we scale up using more qubits. This cracks a key challenge in quantum error correction that the field has pursued for almost 30 years.
- Second, Willow performed a standard benchmark computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion (that is, 1025) years — a number that vastly exceeds the age of the Universe.
