Quantum annealing (QA) is a cutting-edge algorithm that leverages the unique properties of quantum computing to tackle complex combinatorial optimization problems (a class of mathematical problems ...

We talk a lot about quantum computation and quantum key distribution here at Ars, but when we do this, we’re usually talking about a discrete logic system. That is, the quantum system uses a set of ...

Scientists believe that time is continuous, not discrete—roughly speaking, they believe that it does not progress in "chunks," but rather "flows," smoothly and continuously. So they often model the ...
