Quantum state tomography, entanglement detection and Bell violation prospects in weak decays of massive particles
Abstract A rather general method for determining the spin density matrix of a multi-particle system from angular decay data is presented. The method is based on a Bloch parameterisation of the d-dimensional generalised Gell-Mann representation of ρ and exploits the associated Wigner- and Weyl-transf...
