Google claims to have reached quantum supremacy

Quantum supremacy is the potential capacity of quantum computing devices to solve problems that classical computers can hardly solve.

As you all know, quantum computing is based on quantum physics. This uses qubits instead of bits, which have the ability to have a value of 0 and 1 simultaneously, which accelerates certain types of calculations.

According to Google researchers, its technology was able to perform in three minutes and 20 seconds, a calculation that today's biggest super computer, called Summit, would take 10,000 years to solve.

That is why they claim to have achieved quantum supremacy. The real fact is that the calculation they have made is of little use beyond verifying this fact.

In reality, this system can only perform a unique and highly technical calculation, so the use of quantum computers to solve useful problems has yet to wait a decade.
