    "abstract": "We present an approach to the unconditional security of quantum key\ndistribution protocols based on the uncertainty principle. The approach applies\nto every case that has been treated via the argument by Shor and Preskill, and\nrelieve them from the constraints of finding quantum error correcting codes. It\ncan also treat the cases with uncharacterized apparatuses. We derive a secure\nkey rate for the Bennett-Brassard-1984 protocol with an arbitrary source\ncharacterized only by a single parameter representing the basis dependence.",
