Summary

Google announced it achieved 'Verifiable Quantum Advantage'.
The 105-qubit quantum chip 'Willow' was reported to have demonstrated 99.9% operation accuracy.
Experts evaluated that this achievement will likely expand applicability in various fields such as finance.

Google announced that its quantum computing division has achieved 'Verifiable Quantum Advantage.' This is evaluated as the first case to actually demonstrate computations that cannot be performed by conventional computers.

On the 22nd (local time), according to financial news channel Walter Bloomberg, the Google Quantum AI team said the 105-qubit-based quantum chip 'Willow' achieved up to 99.9% operation accuracy. The chip is reported to have performed millions of operations in just a few seconds.

Google also explained that by applying the new quantum algorithm 'Quantum Echoes', it processed operations that are impossible for existing supercomputers. This achievement is regarded as an important milestone showing that quantum computing is entering the stage of practical computation.

Experts analyzed, "It is significant that Google presented the experimental data in a publicly verifiable form," and "the applicability is expected to expand in various fields such as finance, materials engineering, and cryptanalysis in the future."
