Query: A scheme for quantum communication using EPR pairs and local measurement   We present a scheme for quantum communication, where a set of EPR pairs,
initially shared by the sender Alice and the receiver Bob, functions as a
quantum channel. After insuring the safety of the quantum channel, Alice
applies local measurement on her particles of the EPR pairs and informs Bob the
encoding classical information publicly. According to Alice's classical
information and his measurement outcomes on the EPR pairs Bob can infer the
secret messages directly. In this scheme, to transmit one bit secret message,
the sender Alice only needs to send one bit classical information to the
receiver Bob. We also show that this scheme is completely secure if perfect
quantum channel is used.
