IBM’s new quantum computer is twice the size of China’s Jiuzhang 2

Computer giant IBM has announced that it has built the world’s largest superconducting quantum computer called the Eagle. press release reveals. The new machine is bigger than Google’s Sycamore, as well as China’s Jiuzhang 2.

In October, researchers from China Hefei University of Science and Technology (USTC) announced that their quantum computer Jiuzhang 2 works with 60 superconducting qubits and is incredibly 10 million times faster than Google’s Sycamore quantum computer.

IBM’s new Eagle processor will now double in size Jiuzhang 2 by using 127 qubits to solve problems. This is the latest development in the race to build a quantum computing device that can be used for practical applications, led by Google’s announcement of quantum supremacy in 2019 with its Sycamore processor, which uses the same superconducting architecture as the new Eagle processor. of IBM and Chinese Jiuzhang 2.

The term quantum superiority refers to the successful achievement of a calculation by a quantum computer, which would be impossible for a classical computer to achieve. IBM has challenged before Google’s claim that it has reached quantum supremacy, saying the search firm greatly exaggerates the difficulty of the tasks its Sycamore computer performs.

Quantum computing can deal with the biggest problems of our time

IBM’s 127-qubit Eagle processor is now, in theory, the most powerful quantum computer in the world, although it has yet to be upgraded. Unlike Google and China’s USTC, IBM has not published an academic paper describing detailed tests performed on its quantum computer to demonstrate its performance. The number of qubits is also not everything when it comes to quantum computing power. IN Jiuzhang 2, for example, had a total of 66 qubits and was 10 million times faster than Google’s 54-cubic-meter Sycamorewhich is due in part to its use of light photons.

However, IBM cites impressive statistics for Eagle in its statement. The company claims that the number of classical calculation bits needed to represent the state of the new Eagle processor would be greater than the number of atoms in the entire living human population of approximately 7.5 billion people.

“Quantum computing has the power to transform almost any sector and help us deal with the biggest problems of our time,” said Dr. Dario Gill, senior vice president, IBM and director of research. “The arrival of the Eagle processor is a big step towards a day when quantum computers can outperform classic computers for useful applications,” he continued.

IBM disclosed a roadmap for quantum calculations last year, in which he revealed his plans to demonstrate a 400-qubit processor next year, before building a 1,000-qubit quantum computing chip called the Condor by 2024.
