    "abstract": "With the help of a simple quantum key distribution (QKD) scheme, we discuss\nthe relation between BB84-type protocols and two-step-type ones. It is shown\nthat they have the same essence, i.e., information-splitting. More\nspecifically, the similarity between them includes (1) the carrier state is\nsplit into two parts which will be sent one by one; (2) the possible states of\neach quantum part are indistinguishable; (3) anyone who obtains both parts can\nrecover the initial carrier state and then distinguish it from several possible\nstates. This result is useful for related scheme designing and security\nanalyzing.",
