IBM has created the world’s largest superconducting quantum computer as of 2021.
The tech company developed a 127-qubit quantum computer. This is over double the size of comparable machines made by Google in 2019 and the University of Science and Technology of China in 2020.
IBM claims it has created the world’s largest superconducting quantum computer, surpassing the size of state-of-the-art machines from Google and from researchers at a Chinese university. Previous devices have demonstrated up to 60 superconducting qubits, or quantum bits, working together to solve problems, but IBM’s new Eagle processor more than doubles that by stringing together 127.
