Google announced that its quantum artificial intelligence team has successfully verified a new technology called "Magic State Cultivation" on the Willow quantum chip, reducing the error rate of specific quantum states by about 40 times and achieving an accuracy of 99.99% for the prepared quantum states. The relevant research findings have been published in the journal Science.

Google explains that quantum computers are susceptible to interference, which can lead to errors. To perform complex calculations, it is necessary to prepare special quantum states in advance, but this process consumes a great deal of computational resources. Some studies estimate that traditional methods may utilize up to 95% of the computational power of quantum computers.

Google stated that this new technology improves preparation efficiency by detecting and eliminating erroneous quantum states, which is expected to reduce the resource consumption of future quantum computers in terms of error correction. Google claims that this achievement is an important step towards practical quantum computing, but further verification is still needed to determine whether it can be applied to larger-scale quantum computing systems.
