Coherent communication of classical messages.
We define coherent communication in terms of a simple primitive, show it is equivalent to the ability to send a classical message with a unitary or isometric operation, and use it to relate other resources in quantum information theory. Using coherent communication, we are able to generalize superdense coding to prepare arbitrary quantum states instead of only classical messages. We also derive...
متن کاملBidirectional coherent classical communication
A unitary interaction coupling two parties enables quantum or classical communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff between the achievable rates of specific types of forward and backward communication. Our first result shows that for any bipartite unitary gate, bidirectional coherent classical communication is no more di...
متن کاملNonverbal Messages and Intercultural Communication
Intercultural communication takes place when individuals influenced by different cultural communities negotiate shared meanings in interaction. As every country has its own cultural value system; consequently, nonverbal communication is different from country to country. Therefore, having knowledge about the similarities and differences of nonverbal communication in different cultures increases...
متن کاملSimultaneous Communication Protocols with Quantum and Classical Messages
We study the simultaneous message passing (SMP) model of communication complexity, for the case where one party is quantum and the other is classical. We show that in an SMP protocol that computes some function with the first party sending q qubits and the second sending c classical bits, the quantum message can be replaced by a randomized message of O(qc) classical bits, as well as by a determ...
