Google has made a significant breakthrough in the field of quantum computing with the development of a quantum supercomputer with 70 qubits. This makes it 241 million times more powerful than its predecessor.

Google's quantum computer would have demonstrated its ability to overcome interference and operate beyond classical computing. The most powerful supercomputer, Frontier, would take 47 years as long as Google's quantum computer takes a second. It's 1.483 billion times more powerful, according to Google.

"We presented a RCS experiment with 70 qubits at 24 cycles. We calculate the computational cost by comparing it with improved classical methods and demonstrate that our experiment exceeds the capabilities of existing classic supercomputers," Google explains.

Research shows that larger quantum computers can effectively manage the noise that can disrupt qubits operations, making calculations more reliable.

Critics argue that Google exaggerates when comparing the performance of your computer with quantum supercomputers, and that the calculations used in research do not have a practical application.

Proponents of quantum computers believe that this technology has the potential to address important challenges such as climate change and drug discovery.

This advance of Google represents an important milestone in the development of quantum computing and paves the way for new advances in this field.

Microsoft and IBM advance in quantum computing

Recently, Microsoft announced a major breakthrough in its project of building a quantum supercomputer by creating and controlling the Majorana particle, fundamental to the creation of qubits, quantum information units.

IBM, for its part, made significant progress in quantum computing technology with its 127 qubits Eagle processor and hopes to present its most powerful processor so far, the 1.121 qubits Condor chip, by the end of this year.
