    • Our definition of finite references differs from the bounded references of Bartlett. In the latter case the bound is on some physical parameter of the reference such as the number of spin-1/2 particles or the mean photon number. In particular, bounded references can have either finite- or infinite-dimensional state spaces. In contrast, a finite reference is associated with a finite-dimensional state space. This state space could be a fixed subspace of an infinite-dimensional Hilbert space. The important point in the context of this paper is that a finite reference has a finite number of adjustable parameters

    • Our constraint of a fixed number of particles means that it is not possible to make a direct comparison between the reference states considered in this paper and van Enk's refbit state which is based on an uncertain number of shared particles.

    • In contrast, the state |n is invariant to the group operation T (Φ) in the sense that T (Φ) |n n| T † (Φ) = |n n|, which illustrates the symmetry of |n with respect to U(1).
