AbstractMany entanglement distillation schemes use either universal random hashing or breeding as their final step to obtain almost perfect shared EPR pairs spite of a high yield, the hardness of decoding a random linear code makes the use of random hashing and breeding infeasible in practice this pilot study, we analyze the performance of the recurrence method, a well-known entanglement distillation scheme, with its final random hashing or breeding procedure being replaced by various efficiently decodable quantum codes. Among all the replacements investigated, the one using a certain adaptive quantum low density parity check (QLDPC) code is found to give the highest yield for Werner states over a wide range of noise level- the yield for using this QLDPC code is higher than the first runner up by more than 25% over a wide parameter range this respect, the effectiveness of using QLDPC codes in practical entanglement distillation is illustrated. © The Author(s) 2010.
