It’s not often that 5-year-olds can grasp questions at the frontiers of computer science, but it can happen. Suppose, for instance, that a kindergartner named Alice has two apples, but she prefers ...

Scientists have established a relationship between the complexity of a problem, and the physical processes of entanglement required to solve it. “Some mathematical problems are easy. Some mathematical ...

Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex computational problems, with applications in everything from supply chain ...
