Intel has built a quantum processor called Tunnel Falls that it will offer to research labs hoping to make the revolutionary computing technology practical. The Tunnel Falls processor, announced Thursday, houses 12 of the fundamental data processing elements called qubits. It's a major step in the chipmaker's attempt to develop quantum computing hardware it hopes will eventually surpass rivals. Intel, unlike most of its rivals, makes its qubits from individual electrons housed in computer chips that are cousins to those that power millions of PCs. The company is lagging behind. Rivals like IBM, Google, Quantinuum and IonQ have been offering quantum computers for years, but Intel believes tying its fortunes to conventional chip technology will ultimately enable faster progress.
