Google Releases Cross-Era Quantum Chip Willow

Google CEO Pichai excitedly announced the latest quantum computing chip Willow has come out just now!

Willow has achieved amazing results in the benchmark test: it completed a standard calculation in less than 5 minutes, which required top-notch supercomputing for more than 10^25 years-longer than the age of the universe!

Willow is not only a victory of speed, but also a decisive technical breakthrough in the field of quantum computing-with the increase of the number of qubits, the error of this chip also decreases exponentially. The rate of this accuracy improvement exceeds a critical threshold. This means that the problem of error correction that has plagued quantum computing for nearly 30 years has finally ushered in the dawn. The latest research of Google Quantum Team has been published in today's Nature journal.

The method adopted by Google is to correct errors through a 'grid' arrangement. Willow uses a 7X7 grid arrangement, in which 49 quanta are used as data bits and an additional 48 quanta are used for measurement. In this way, Google "breaks through the error correction equilibrium point", that is, after adding bits, it can achieve fewer errors.

This is a major breakthrough since computer scientist Peter Shor proposed the concept of 'quantum error correction' in 1995. According to a paper published by Google, if qubits are further increased in the future, the error rate will decrease exponentially, to the order of 10^-10.

When the news came out, Musk was amazed: "Wow!" This chip has won praises from many technology giants such as Musk and Altman.

Hartmut Neven, founder of Google Quantum AI, claimed in a blog post that the computing speed of the Willow chip is so amazing that it appears to have "borrowed" computing power from other universes.

Google's stock price soared immediately after Willow was released, rising 10% in two days. Bitcoin prices fell in response, falling 6% at the lowest.
