Topological quantum computation
... nor fermions are called anyons. Anyons are a fascinating theoretical construct, but do they have anything to do with the physics of real systems that can be studied in the laboratory? The remarkable answer is: “Yes!” Even in our three-dimensional world, a two-dimensional gas of electrons can be real ...

Finding ordinary objects in some quantum worlds
... H. There is nothing more to the world beyond the facts that constitute the wavefunction and govern its evolution. There is, for example, no further location relation assigning each particle to a point of space at each time.6 If there is any sense in which particles at a H-world can be described as h ...
