Google has unveiled its new Willow quantum processor, which, according to the company, significantly outperforms existing supercomputers in terms of speed, completing a task that would take even the fastest supercomputer 10 septillion years to complete. A key achievement is the exponential reduction in the error rate as the number of qubits increases, which is considered a breakthrough in quantum computing. Google attributes the high speed to computations in parallel universes, claiming that this supports the multiverse hypothesis. Although Willow does not yet solve practical problems, Google sees it as an important step toward creating useful quantum computers.

How does Google Willow use quantum computing to solve complex problems?

Google uses quantum computing to solve complex problems by developing quantum processors such as Willow. Willow, a 105-qubit processor, has demonstrated superiority over classical supercomputers in performing certain computations.

What are the key features of Google's use of quantum computing?

Superior performance: Willow completed a standard benchmark test in less than five minutes, whereas one of the world's fastest supercomputers would take 10 septillion years to complete the same task.

Reducing the error rate: Google has succeeded in reducing the error rate as the system scales up, which is an important milestone in quantum computing.

Focus on Quality: Google emphasizes the importance of the quality of qubits, not just their quantity.

Although Willow is not yet ready to solve practical problems, Google believes that quantum computing could revolutionize various fields, including: Drug development, the design of more efficient batteries, and accelerating progress in fusion energy and alternative energy.

The head of Google Quantum AI is confident that the joint development of quantum computing and artificial intelligence will open up new opportunities for research in various fields.

What problem did the Willow processor solve faster than the Frontier supercomputer?

Google's Willow processor outperformed the Frontier supercomputer in solving a problem based on Random Circuit Sampling (RCS) benchmark.

RCS – This is a test developed by Google to demonstrate the advantages of quantum computers over classical ones.

The Essence of RCS:

1. A quantum circuit is created from a random set of logical operations.
2. This program runs on a quantum computer.
3. The results are compared with the results of simulations run on a classical computer.

Willow completed the RCS in less than five minutes, whereas Frontier would have taken 10 septillion years to do so. It is important to note that the sources do not specify exactly which logical operations were used in the RCS benchmark.
