    "abstract": "We present a family of entanglement purification protocols that generalize\nfour previous methods, namely the recurrence method, the modified recurrence\nmethod, and the two methods proposed by Maneva-Smolin and Leung-Shor. We will\nshow that this family of protocols have improved yields over a wide range of\ninitial fidelities F, and hence imply new lower bounds on the quantum capacity\nassisted by two-way classical communication of the quantum depolarizing\nchannel. In particular, the yields of these protocols are higher than the yield\nof universal hashing for F less than 0.993 and as F goes to 1.",
