Dense coding with multipartite quantum states
We consider generalisations of the dense coding protocol with an arbitrary number of senders and either one or two receivers, sharing a multiparty quantum state, and using a noiseless channel. For the case of a single receiver, the capacity of such information transfer is found exactly. It is shown that the capacity is not enhanced by allowing the senders to perform joint operations. We provide...
متن کاملTeleportation and dense coding with genuine multipartite entanglement.
We present an explicit protocol E0 for faithfully teleporting an arbitrary two-qubit state via a genuine four-qubit entangled state. By construction, our four-partite state is not reducible to a pair of Bell states. Its properties are compared and contrasted with those of the four-party Greenberger-Horne-Zeilinger and W states. We also give a dense coding scheme D0 involving our state as a shar...
متن کاملApproximate and Multipartite Quantum Correlation (Communication) Complexity
The concepts of quantum correlation and communication complexity have been proposed to quantify the worst-case computational resources needed in generating bipartite classical distributions or bipartite quantum states in the single-shot setting by Zhang (Proc. 3rd Innov Theor Comput., pp. 39-59, 2012). The former characterizes the minimal size of the initial shared state needed if no communicat...
متن کاملQuantum correlations require multipartite information principles.
Identifying which correlations among distant observers are possible within our current description of nature, based on quantum mechanics, is a fundamental problem in physics. Recently, information concepts have been proposed as the key ingredient to characterize the set of quantum correlations. Novel information principles, such as information causality or nontrivial communication complexity, h...
متن کاملDense coding and safety of quantum communications
Safety of quantum communications is, in the first place, the result of the quantum nature of the signal, sending by the sender Alice to the receiver Bob [1], [2], [3]. But when we discuss the safety of the quantum communications as a whole we have to take into account all objects taking place in the process of creation and communication of information. One of such object is the sending station,...
