DESCRIPTION:Speaker: Jan Philip Solovej\nhosted by Robert Seiringer\nAbstra
 ct: For a group G we study quantum channels\, i.e.\, completely positive t
 race preserving maps between operators on irreducible unitary representati
 ons of the group that intertwine the group action\, i.e.\, are eqivariant.
  We will mainly focus on G=SU(2) but also discuss SU(d) for d>2. It turns 
 out that the set of equivariant SU(2) channels forms a finite dimensional 
 simplex and we will describe the critical points and give several ways to 
 represent them. Using majorization we will determine the minimal output en
 tropy of two of these extremal channels. Generalizations to SU(2) and seve
 ral open questions will be discussed
