Quantum tug of war between randomness and symmetries on homogeneous spaces

We explore the interplay between symmetry and randomness in quantum information. Adopting a geometric approach, we consider states as H equivalent if related by a symmetry transformation characterized by the group H. We then introduce the Haar measure on the homogeneous space U/H, characterizing tru...
