The cube is one example of a small group of regular polyhedra—solid bodies with flat planes for faces, which satisfy the symmetry requirement that every face, every edge, and every corner should be precisely th ...

`Nonclassical` states in quantum optics: a `squeezed` review of the

Another example of a ‘nonclassical’ state is a superposition of two different coherent states [33]. As a matter of fact, all pure states, excepting the coherent states, are ‘n ...
