Scientists may have uncovered the missing piece of quantum computing by reviving a particle once dismissed as useless. This particle, called the neglecton, could give fragile quantum systems the full ...

For the past year, I kept bringing the same story to my editor: quantum computers are on the edge of becoming useful for scientific discovery. Of course, that has always been the goal. The idea of ...

Large quantum computers may be able to solve problems impossible for even the best traditional supercomputers – but in order to do so, some of them might need far more energy than those supercomputers ...
