We consider four locations A, B, C and D with specified distance. At first, the entangled states for locations (A, B) and (C, D) have been produced separately by using beam splitter. Finally, the entanglement from the entangled states (A, B) and (C, D) is swapped to the pair (A, D) using Bell state measurement method. The locations can be easily generalized to locations where and so one can introduce this model as a quantum repeater. CP - IRAN IN - LG - eng PB - opsi PG - 9 PT - Research YR - 2019
