IBM plans to build the largest quantum computer to date, linking smaller machines together to create a large number of quantum bits, or qubits. The company’s first steps in that direction in 2025 should achieve a new qubit record, eventually more than tripling the size of the largest quantum computer in existence.
Only six years have passed since then IBM unveiled its first commercial quantum computer. That device contained 20 qubits, the basic building blocks of any quantum…
