In this work, we present anextension of the MaxEnt principle, adapted to estimate quantum statesusing a priori information given in terms of symmetries of thesystem. Our approach can be applied to very general situations,including symmetries represented by Lie groups and finite groups. Weobserve that using the symmetry information it is possible to reducethe number of necessary measurements to make a good estimation. p { margin-bottom: 0.25cm; direction: ltr; line-height: 115%; text-align: left; orphans: 2; widows: 2; background: transparent }a:link { color: #0000ff; text-decoration: underline }
