The requirements for a functional quantum computer have been summarised by DiVincenzo [12]: it is imperative to be able to initialise a well-defined quantum register, to manipulate it and be able to retrieve the information before the information is lost. These criteria have originally been suggeste ...

“Anticoherent” Spin States via the Majorana Representation
... B. A Tetrahedral Basis in C5 Five tetrahedra can be oriented in space in an interlocking fashion so that their twenty vertices together comprise the vertices of a dodecahedron. (See Fig. 2.) This configuration offers a highly symmetrical way of inscribing five tetrahedra in the sphere. Now, as the t ...
