(FierceElectronics) Computing giant IBM announced that it has built the world’s largest superconducting quantum computer, called Eagle, a press statement reveals. The new machine is larger than Google’s Sycamore as well as China’s Jiuzhang 2.
In October, researchers at China’s University of Science and Technology (USTC) in Hefei announced that their quantum computer Jiuzhang 2 worked using 60 superconducting qubits, and that it was a staggering 10 million times faster than Google’s Sycamore quantum computer.
Now, IBM’s new Eagle processor will more than double the size of Jiuzhang 2 by using 127 qubits to solve problems.
IBM’s 127-qubit Eagle processor is now, theoretically speaking, the most powerful quantum computer in the world, though it is yet to be put through its paces. Unlike Google and China’s USTC, IBM hasn’t published an academic paper detailing tests conducted on its quantum computer to demonstrate its performance. Qubits count is also not the be all and end all when it comes to quantum computing power. The Jiuzhang 2, for example, had a total of 66 qubits, and it was 10 million times faster than Google’s 54-qubit Sycamore, due, in part, to its use of light photons.
“Quantum computing has the power to transform nearly every sector and help us tackle the biggest problems of our time,” said Dr. Darío Gil, Senior Vice President, IBM and Director of Research. “The arrival of the Eagle processor is a major step towards the day when quantum computers can outperform classical computers for useful applications,” he continued.
