IBM unveils world’s most powerful quantum computer

On Tuesday (16) IBM will unveil the world’s most powerful quantum computer. Dubbed the Eagle, the device runs on 127 quantum bits, or qubits, and, according to the company, has twice the power of Zuchongzhi, the Chinese quantum computer unveiled in July of this year.

At that time, the Chinese machine, containing 56 qubits, was considered the most powerful in the world in its class, having solved in about 70 minutes a task that “classic” supercomputers would take at least eight years.

“Eagle is an important step because it has crossed the 100-qubit barrier. It has already reached the limit where its computing power can no longer be simulated using conventional processors,” Zaira Nazario, Technical Director of Quantum Computing Theory and Its Applications, told the newspaper. Country. The number of classical bits needed to match the computing power of the new processor exceeds the total number of atoms for more than 7.5 billion people living today.

“The arrival of the Eagle processor is an important step toward the day when quantum computers will be able to significantly outperform classical computers,” said Dário Gil, Vice President and Director of Research at IBM.

Quantum computers are not yet widely used, but they have the potential to revolutionize our society more intensively than the “classical” computers currently in use.

By harnessing Qubits’ ability to assume multiple states at once (a phenomenon called superposition), they can handle problems that would be impossible or time-consuming to solve on a regular PC.

Among the tasks that make it possible to crack, in seconds, are encryption algorithms that would take millions of years to decode on a conventional computer, to simulate the interaction of molecules in the development of chemicals and medicines, or even seemingly “ordinary” tasks of how to calculate the best route for parcel delivery. Or which investment portfolio will yield the best return.

IBM, one of the leaders in quantum computing, hopes to introduce a new processor of 433 qubits next year, and in 2023 another processor of 1,121 qubits.
