摘要：

In the present work, we study the entanglement swapping via the two-photon process without explicitly using the Bell-state measurement. We employ the appropriate 'full two-photon Hamiltonian approach' instead of the 'effective Hamiltonian approach' used in recent schemes. We obtain entanglement swapping with 94.7% fidelity for maximally entangled states by conveniently choosing the atom-field interaction time. The success probability is also considered.
