    "abstract": "We present an one-time-pad key communication protocol that allows secure\ndirect communication with entanglement. Alice can send message to Bob in a\ndeterministic manner by using local measurements and public communication. The\ntheoretical efficiency of this protocol is double compared with BB84 protocol.\nWe show this protocol is unconditional secure under arbitrary quantum attack.\nAnd we discuss that this protocol can be perfectly implemented with current\ntechnologies.",
