Inherent to Dirac equation there are two discrete degrees of freedom, the intrinsic parity and the spin, supporting the interpretation of the Dirac bi-spinors as two-qubit states. In particular, the eigenstates of Dirac equation in general are entangled states with respect to these two internal degress of freedom. In this seminar, the intrinsic spin-parity entanglement properties of Dirac bi-spinors are described in a generic framework, considering the influence of constant external potentials in the entanglement properties of Dirac equation solutions.
