Scientific paper

We present an encoded hybrid quantum repeater scheme using qubit-repetition codes and Calderbank-Shor-Steane codes. For the case of repetition codes, we propose an explicit implementation of the quantum error correction protocol. Moreover, we analyze the entangled-pair distribution rate for the hybrid quantum repeater with encoding and we clearly identify a triple trade-off between the efficiency of the codes, the memory decoherence time, and the local gate errors. Finally, we show that in the presence of reasonable imperfections our system can achieve rates of roughly 40 Hz per memory for 20 km repeater spacing, a final distance of 1280 km, and final fidelity of about 0.95.
