Google’s quantum computer can complete tasks beyond the reach of any classic supercomputer

Google’s quantum computer can complete tasks beyond the reach of any classic supercomputer

Google researchers argue that the new quantum computer for the first time able to perform tasks not available even to the fastest classic supercomputers.

So, the company developed a 53-bit quantuma computer for calculating math problems in 200 seconds called Sycamore. According to the article, the fastest supercomputers in the world will need more than 10,000 years to solve the same problem. Sycamore’s ability to do fast computing makes it useful for creating verifiable random numbers, optimizations, machine learning, etc.

While ordinary computers storeinformation in bits (1 or 0), quantum computers use quantum bits, which can simultaneously be either 1 or 0. This so-called “superposition” state allows quantum computers to reach speeds inaccessible to classical computers.

However, at the moment, a quantum computerGoogle is still unable to run well-known quantum algorithms, such as the Shore algorithm, which, if implemented, could pose a threat to the existing public key encryption scheme.
