We show that in prime dimensions not equal to 3, each group covariant symmetric informationally complete positive operator valued measure (SIC POVM) is covariant with respect to a unique Heisenberg–Weyl (HW) group. Moreover, the symmetry group of the SIC POVM is a subgroup of the Clifford group. Hence, two SIC POVMs covariant with respect to the HW group are unitarily or antiunitarily equivalent if and only if they are on the same orbit of the extended Clifford group. In dimension 3, each group…

Galois automorphisms of a symmetric measurement
The Galois group of SICs covariant with respect to the Weyl-Heisenberg group is examined and a list of nine conjectures concerning its structure are proposed, representing a considerable strengthening of the theorems actually proved.
Super-symmetric informationally complete measurements
The existence of a set of d pairwise equiangular complex lines (a SIC-POVM) in ddimensional Hilbert space is currently known only for a finite set of dimensions d. We prove that, if there exists a
Systems of imprimitivity for the clifford group
It is known that if the dimension is a perfect square the Clifford group can be represented by monomial matrices. Another way of expressing this result is to say that when the dimension is a perfect
Group theoretic, lie algebraic and Jordan algebraic formulations of the sic existence problem
The purpose of this paper is to show that the SIC existence problem is equivalent to three other, on the face of it quite different problems, although it is still not clear whether these reformulations of the problem will make it more tractable.

We consider the question of the existence of d2 equiangular lines in d-dimensional complex space Cd. In physics, such a set of equiangular lines is called a symmetric, informationally complete
Linear dependencies in Weyl–Heisenberg orbits
It is proved that linear dependencies will always emerge in Weyl–Heisenberg orbits when the fiducial vector lies in a certain subspace of an order 3 unitary matrix, and this work aligns with recent studies on representations of the Clifford group.

The existence of $d^2$ pairwise equiangular complex lines [equivalently, a symmetric informationally complete positive operator-valued measure (SIC-POVM)] in $d$-dimensional Hilbert space is known
A remarkable representation of the Clifford group
The finite Heisenberg group knows when the dimension of Hilbert space is a square number. Remarkably, it then admits a representation such that the entire Clifford group—the automorphism group of the
Dimension towers of SICs. I. Aligned SICs and embedded tight frames
It is proven that a complete set of mutually unbiased bases can be obtained by reducing an aligned SIC to this dimension, and if d − 2 is an odd prime number, it is proved that the individual vectors in thealigned SIC have a very special entanglement structure.

The paper concerns Weyl‐Heisenberg covariant SIC‐POVMs (symmetric informationally complete positive operator valued measures) and full sets of MUBs (mutually unbiased bases) in prime dimension. When

It is conjecture that a particular kind of group-covariant SIC–POVM exists in arbitrary dimensions, providing numerical results up to dimension 45 to bolster this claim.
