Hyperdense coding and superadditivity of classical capacities in hypersphere theories
New Journal of Physics, 2015 In quantum superdense coding, two parties previously sharing entanglement can communicate a two bit message by sending a single qubit. We study this feature in the broader framework of general probabilistic theories.

The states of W-class as shared resources for perfect teleportation and superdense coding [PDF]
, 2007 As we know, the states of triqubit systems have two important classes: GHZ-class and W-class. In this paper, the states of W-class are considered for teleportation and superdense coding, and are generalized to multi-particle systems.

Superdense Coding with GHZ and Quantum Key Distribution with W in the ZX-calculus [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 Quantum entanglement is a key resource in many quantum protocols, such as quantum teleportation and quantum cryptography. Yet entanglement makes protocols presented in Dirac notation difficult to verify.

N-qubit quantum teleportation, information splitting and superdense coding through the composite GHZ–Bell channel [PDF]
, 2011 We introduce a general odd qubit entangled system composed of GHZ and Bell pairs and explicate its usefulness for quantum teleportation, information splitting and superdense coding.

Four-dimensional entanglement distribution over 100 km [PDF]
Scientific Reports, 2018 High-dimensional quantum entanglement can enrich the functionality of quantum information processing. For example, it can enhance the channel capacity for linear optic superdense coding and decrease the error rate threshold of quantum key distribution ...

Perfect teleportation and superdense coding with
, 2006 True tripartite entanglement of the state of a system of three qubits can be classified on the basis of stochastic local operations and classical communications (SLOCC). Such states can be classified in two categories: GHZ states and W-states.

Superdense coding using multipartite states
, 2004 We show that with the fourpartite quantum channel used to teleport an arbitrary two qubit state, we can construct a superdense coding protocol where it is possible to transmit 4 bits of classical information sending only 2 qubits. Alice and Bob initially share a four qubit maximally entangled state and by locally manipulating her two qubits Alice can ...

A SUFFICIENT AND NECESSARY CONDITION FOR SUPERDENSE CODING OF QUANTUM STATES [PDF]
International Journal of Quantum Information, 2008 Recently, Harrow et al. [Phys. Rev. Lett.92 (2004) 187901] gave a method for preparing an arbitrary quantum state with high success probability by physically transmitting some qubits, and by consuming a maximally entangled state, together with exhausting some shared random bits.

Probabilistic superdense coding [PDF]
Physical Review A, 2005 We explore the possibility of performing super dense coding with non-maximally entangled states as a resource. Using this we find that one can send two classical bits in a probabilistic manner by sending a qubit. We generalize our scheme to higher dimensions and show that one can communicate 2log_2 d classical bits by sending a d-dimensional quantum ...
