http://research.physics.illinois.edu/QI/Photonics/tomography-files/tomo_chapter_2004.pdf WebThe completely mixed state of a single qubit is represented by the center of the sphere, by symmetry. The purity of a state can be visualized as the degree in which it is close to the surface of the sphere. This concept of representing the state as a matrix, rather than a vector, is often convenient because it gives a convenient way of ...
