Long-distance experiments in quantum information science, and in particular featuring quantum key distribution (QKD), are of the utmost importance for future technological applications. Such ...

Test methods and data acquisition system specifications are described for measurements of the energy consumption of the control system of a servo-pump continuously variable transmission (CVT). Dynamic ...

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 ...
