Abstract: (APS)

We use the concept of quantum entanglement to analyze the Schwinger effect on an entangled state of a qubit and a boson mode coupled with the electric field. As a consequence of the Schwinger production of particle-antiparticle pairs, the electric field decreases both the correlation and the entanglement between the qubit and the particle mode. This work exposes a profound difference between bosons and fermions. In the boson case, entanglement between the qubit and the antiparticle mode cannot be caused by the Schwinger effect on the preexisting entanglement between the qubit and the particle mode, though correlation can. In the fermion case, both can.
