Abstract

The Schwinger effect on the entanglement of a hybrid state is studied in this paper. We consider a system composed of a qubit and a bosonic mode. We show that when only the bosonic mode is coupled with a constant electric field, entanglement depends on the strength of the electric field. The results show that the entanglement between the qubit and the bosonic particle decreases with increasing the value of the electric field. Furthermore, applying the electric field creates entanglement between the qubit and antiparticle mode where initially there is no entanglement between them. Moreover, we analyze the variation of entanglement with respect to other parameters such as the mass of the particles and the parameter of hybrid state, \(\alpha \).
