Google claims to have demonstrated something called “quantum supremacy,” in a paper published in Nature. This would mark a significant milestone in the development of a new type of computer, known as a quantum computer, that could perform very difficult calculations much faster than anything possible on conventional “classical” computers. But a team from IBM has published its own paper claiming it can reproduce the Google result on existing supercomputers.

While Google vs. IBM might make a good story, this disagreement between two of the world’s biggest technology companies rather distracts from the real scientific and technological progress behind both teams’ work. Despite how it might sound, even exceeding the milestone of quantum supremacy wouldn’t mean quantum computers are about to take over. On the other hand, just approaching this point has exciting implications for the future of technology.
