Abstract

This paper collects miscellaneous results about the group SU(1, 1) that are helpful in applications in quantum optics. Moreover, we derive two new results, the first of which is about the approximability of SU(1, 1) elements by a finite set of elementary gates and the second of which is about the regularization of group identities for tomographic purposes.
