In this work, we propose a measure for the quantum discord of indistinguishable particles, based on the definition of entanglement of particles given in Wiseman and Vaccaro (Phys Rev Lett 91:097902, 2003 . doi: 10.1103/PhysRevLett.91.097902 ). This discord of particles is then used to evaluate the q...
