Google announces the latest quantum algorithms in the real world with excessive frequency

Google Quantum AI researchers report that their Willow quantum processor ran a quantum computing algorithm that solved a complex physics problem thousands of times faster than the world's most powerful computers.If confirmed, it will be one of the first demonstrations of practical computing, where a quantum computer solves real-world problems faster and more accurately than a classical computer.

In a new paper published in the journal Nature, the researchers describe how their algorithm, called Quantum Echoes, measures the complex behavior of particles in highly entangled quantum systems.These are interconnected systems where multiple cells share the same function even though they are physically separated.If you measure a characteristic of one particle, you instantly know about others.This link makes the whole system very complex and difficult to model on standard computers.

The Quantum Echoes algorithm uses a concept called the Out-of-Time-Order Correlator (OTOC), which measures how fast information propagates and propagates in a quantum system.The researchers chose this particular measurement because, as they point out in the paper, "OTOCs have a quantum disorder effect that makes them very sensitive to the details of quantum dynamics, and for OTOC (2) there is also a high level of complexity in classical simulations. Therefore, OTOCs are viable candidates for realizing practical quantum advantages."

The algorithm is based on a clever "time reversal trick".A quantum computer drives the system forward, moves it a little, and then precisely reverses the process.In this experiment, they used second-order OTOC-OTOC (2), a more complex form of OTOC.createsIn this task, which examines how fast information travels in a complex quantum state, the quantum chip performed calculations 13,000 times faster than the world's fastest supercomputer.

This is not the first time that the Google team has shown its originality.In 2019, they claimed "Quantity Squintacy" After Chipaddamar and Sycamore Chip solved the technical problem much faster than the seller.However, what makes this different is that during the previous test he focused on solving the traditional problem (which results in solving a physics problem.

Ultimately, this research means we could be getting closer to the day when quantum computers are routinely used to solve complex problems that are currently beyond the reach of supercomputers.This could include discovering new materials, designing better medicines and creating more accurate climate models.
