... • This principle states that you cannot know both the position and momentum of a particle simultaneously to arbitrary accuracy. – There are many approaches to this idea. Here are two. • The act of measuring position requires that the particle intact with a probe, which imparts momentum to the partic ...

Fault-tolerant quantum computation
... In topological quantum computing, quantum gates are protected from noise at the physical level. Here, too, the key notion is that by encoding quantum information nonlocally (in the fusion spaces of many nonabelian anyons) it can be protected against damage due to local noise. [Freedman talk] Methods ...

... properties of not only particles, but also waves. It addresses the inability of the classical concepts "particle" or "wave" to fully describe the behavior of quantum-scale objects. As Einstein wrote: "It seems as though we must use sometimes the one theory and sometimes the other, while at times we ...
