Literally tiny. As IBM announces a big advance, many challenges remain in building a computer that takes advantage of quantum weirdness.
Quantum computing is not easy. Researchers at IBM recently announced that they had taken a step toward solving one of its biggest challenges: developing a better way to detect and correct annoying errors. In a blog post, Mark Ritter, who oversees scientists and engineers at IBM's T.J. Watson Research Laboratory, says: "I believe we're entering what will come to be seen as the golden age of quantum computing research." His team, he wrote, is "on the forefront of efforts to create the first true quantum computer."
