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 ...

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 ...

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 ...
