Abstract
We describe a recently developed generalization of the PoincarĂ© sphere method, to represent pure states of a threelevel quantum system in a convenient geometrical manner. The construction depends on the properties of the group SU(3) and its generators in the defining representation, and uses geometrical objects and operations in an eightdimensional real Euclidean space. This construction is then used to develop a generalization of the well known Pancharatnam geometric phase formula, for evolution of a threelevel system along a geodesic triangle in state space.
