It might seem an obvious statement that there are limits to what we know, but the principle first expounded by the German physicist Werner Heisenberg in 1927 takes things to a new and weird level. Think of a football. If you kick a football, knowing where it is doesn’t stop you knowing where it’s going, … Read more

In a First, Physicists Glimpse a Quantum Ghost

by

The wave function—an abstract concept used to predict the behavior of quantum particles—is the bedrock on which physicists have built their understanding of quantum mechanics. But this bedrock itself is not something physicists have a perfect grasp of, literally or philosophically. A wave function is not something one can hold in their hand or put … Read more

Reprogrammable Eutelsat Quantum Satellite Shifts Missions on the Fly

by

Companies, governments and other customers will soon be able to directly access instruments on a satellite and assign them new missions on the fly. According to program manager Frédéric Piro, the Eutelsat Quantum, which blasted into space from Kourou in French Guiana this summer, is the world’s first commercial satellite that can be fully reprogrammed … Read more
