Enhanced Superdense Coding over Correlated Amplitude Damping Channel [PDF]
Entropy, 2019 Quantum channels with correlated effects are realistic scenarios for the study of noisy quantum communication when the channels are consecutively used. In this paper, superdense coding is reexamined under a correlated amplitude damping (CAD) channel. Two

Entanglement and Superdense Coding with Linear Optics [PDF]
International Journal of Quantum Information, 2011 We discuss a scheme for a full superdense coding of entangled photon states employing only linear-optics elements. By using the mixed basis consisting of four states that are unambiguously distinguishable by a standard and polarizing beam splitters we ...

Atmospheric implementation of superdense coding quantum algorithm
Physics of Complex Systems, 2022 We consider the properties of a quantum communication channel in open space using the superdense coding algorithm as an example. We studied the theoretical model of the installation that implements this algorithm, and identified the main factors ...

Perfect Teleportation and Superdense Coding With W-States [PDF]
, 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.

On the Storage–Communication Trade-Off in Graph-Based X-Secure T-Private Linear Computation [PDF]
EntropyThe problem of graph-based X-secure T-private linear computation (GXSTPLC) is to allow a user to retrieve a linear combination of K messages from a set of N distributed servers that store the messages in a graph-based fashion, i.e., each message is ...

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.

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.
