Quantum key distribution (QKD) enables the generation of information-theoretic security keys between two parties over insecure quantum channels, with the security of these shared keys guaranteed by ...

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 ...
