We call Kronecker states to the ones who belong to the symmetric subspace of the tensor product of three or more irreducible representations of the symmetric group. They are maximally entangled states, allowing us to consider their applications in many protocols of quantum information. In this talk I will describe a procedure that allows us to compute Kronecker states in three parts and recursively obtain Kronecker states with N parts. I will discuss implications in entanglement concentration protocols, their use in quantum channels to achieve superadditivity of classical channel capacity in quantum channels and the possibility of use them in a quantum error correction protocol. Zoom Link
