Quantum Supermacy : Did Google really achieve?

In 2019 Google announced that it had achieved quantum supremacy, meaning that its quantum computer was able to perform a computation that would be infeasible for a classical computer. However, there has been some debate and criticism about the details of the demonstration, and some experts have questioned whether the achievement of quantum supremacy has been overhyped. It is important to note that while the achievement of quantum supremacy is an important milestone, there is still a long way to go in the development of practical quantum computers, and it is not yet clear what kinds of real-world problems such computers will be able to solve.

what is qauntum supermacy

Quantum supremacy is the term used to describe the point at which a quantum computer is able to perform a computation that is beyond the capabilities of any classical computer. This means that the quantum computer would be able to solve a problem in a significantly shorter amount of time than any classical computer could, given the same input.

Achieving quantum supremacy is seen as an important milestone in the development of quantum computers, as it would demonstrate that these machines are capable of performing certain tasks much faster than classical computers, and could potentially be used to solve problems that are currently intractable using classical methods. However, it is important to note that quantum computers are still in the early stages of development, and it is not yet clear what kinds of real-world problems they will be able to solve or how they will be used in practice.

How quantum computer affect the world

Quantum computers have the potential to revolutionize many different fields by solving problems that are currently intractable using classical computers. For example, they could be used to perform simulations of complex systems, such as molecules or materials, which would have a wide range of applications in fields such as chemistry, materials science, and pharmaceuticals. They could also be used to solve optimization problems, which would have applications in fields such as logistics and finance.

In addition, quantum computers could potentially be used to break many of the encryption algorithms that are currently used to secure online communications, which would have significant implications for cybersecurity. On the other hand, quantum computers could also be used to develop new and more secure forms of encryption, which would help to protect against cyber attacks.

Overall, it is difficult to predict exactly how quantum computers will affect the world, as they are still in the early stages of development and it is not yet clear what kinds of real-world problems they will be able to solve. However, it is clear that they have the potential to greatly impact a wide range of fields and industries.
