| Abstract: | In quantum communication via noisy channels, the error probability scales exponentially with the length of the channel. Quantum repeater can overcome this limitation. An experimentally feasible scheme of quantum repeater is presented. The entanglement is created using atomic ensembles. The swapping and purifying components are implemented by polarizing beam splitters. |
