摘要
A generalized definition of the metric of quantum states is proposed by using the techniques of differential geometry. The metric of quantum state space derived earlier by Anandan is reproduced and verified here by this generalized definition. The metric of quantum states in the configuration space and its possible geometrical framework are explored. Also, invariance of the metric of quantum states under local gauge transformations, coordinate transformations, and the relativistic transformations is discussed.
