    "abstract": "In this paper, we consider a quantum key distribution protocol (QKD) with\ntwo-way classical communication that is assisted by one-time pad encryption. We\npropose a two-way preprocessing that uses one-time pad encryption by previously\nshared secret key, and the net key rate of the QKD with proposed preprocessing\nexceeds the key rate of the QKD without it. The preprocessing is reduced to the\nentanglement distillation protocol with two-way classical communication and\npreviously shared EPR pairs (two-way breeding protocol), and the security of\nQKD with the preprocessing is guaranteed in the same way as Shor and Preskill\u0027s\narguments.",
