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

Classical analogue of quantum superdense coding and communication advantage of a single quantum system [PDF]
Quantum, 2022 We analyze utility of communication channels in absence of any short of quantum or classical correlation shared between the sender and the receiver. To this aim, we propose a class of two-party communication games, and show that the games cannot be won ...

Efficient superdense coding in the presence of non-Markovian noise [PDF]
, 2016 Many quantum information tasks rely on entanglement, which is used as a resource, for example, to enable efficient and secure communication. Typically, noise, accompanied by loss of entanglement, reduces the efficiency of quantum protocols.

Multi-qubit teleportation and multi-bit superdense coding via cascade splitting [PDF]
Optical and quantum electronics, 2023 In this study, we present a simplified version of the quantum teleportation protocol for n -qubits and a generalized version of the superdense coding protocol for n -bits, in both cases, thanks to the cascade splitting technique.

Superdense coding in the resource theory of asymmetry [PDF]
Physical Review A, 2021 We consider a task in which classical information is encoded into a quantum system by an operation restricted by symmetry. The maximum amount of classical information that can be encoded under this restriction, namely the symmetry-restricted classical ...
