Google’s new Willow quantum chip managed to perform the random circuit sampling (RCS) benchmark computation in under five minutes that would normally take one of today’s fastest supercomputers 10 septillion years to complete. This exceeds known timescales in physics and vastly exceeds the age of the universe, thus lending to the credence that quantum computation occurs in many parallel universes.
Willow was fabricated in Google’s state-of-the-art fabrication facility in Santa Barbara, as the team wanted to focu on quality, not just quantity. Why? Simply producing larger numbers of qubits doesn’t help if they’re not high enough quality. Willow’s 105 qubits means that it currently has best-in-class performance across the two system benchmarks: quantum error correction and random circuit sampling.

The next challenge for the field is to demonstrate a first ‘useful, beyond-classical’ computation on today’s quantum chips that is relevant to a real-world application. We’re optimistic that the Willow generation of chips can help us achieve this goal,” said Hartmut Neven, Founder and Lead, Google Quantum AI.
