Quantum physics gets a bad rap. The behaviour of the atoms and particles it describes is often said to be weird, and that weirdness has given rise to all manner of esoteric notions – that we live in a multiverse, say, or that the reality we see isn’t real at all. As a result, we often overlook the fact that quantum physics has had a real effect on our lives: every time you glance at your smartphone, for instance, you are benefiting from quantum phenomena. But the story of what quantum theory is good for doesn’t end there. As our mastery of quantum phenomena advances, a new of crop of technologies designed to harness them more directly promises to have a huge impact on science and society. While quantum teleportation and quantum sensing sound exotic and intriguing, the technology that holds the most transformative potential is the one you have probably already heard of: quantum computing.

Full opinion : As quantum computers mature, they will be transformational. But there are good reasons why we don’t yet know exactly which problems they will excel at – and that makes them all the more exciting.
