Multi-qubit teleportation and multi-bit superdense coding via cascade splitting [PDF]

open access: greenOptical 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.

Generating multi-photon W-like states for perfect quantum teleportation and superdense coding [PDF]

open access: goldQuantum Information Processing, 2016
An interesting aspect of multipartite entanglement is that for perfect teleportation and superdense coding, not the maximally entangled W states but a special class of non-maximally entangled W-like states are required.

Increasing the classical data throughput in quantum networks by combining quantum linear network coding with superdense coding [PDF]

open access: greenPhysical Review A, 2020
This paper shows how network coding and superdense coding can be combined to increase the classical data throughput by a factor $2-\epsilon$ (for arbitrarily small $\epsilon > 0$) compared to the maximum that could be achieved using either network coding

A-unital Operations and Quantum Conditional Entropy [PDF]

open access: yesQuantum, 2022
Negative quantum conditional entropy states are key ingredients for information theoretic tasks such as superdense coding, state merging and one-way entanglement distillation.

Superdense Coding over Optical Fiber Links with Complete Bell-State Measurements [PDF]

open access: greenPhysical Review Letters, 2017
Adopting quantum communication to modern networking requires transmitting quantum information through a fiber-based infrastructure. We report the first demonstration of superdense coding over optical fiber links, taking advantage of a complete Bell-state

Quantum one-time tables for unconditionally secure qubit-commitment [PDF]

open access: yesQuantum, 2021
The commodity-based cryptography is an alternative approach to realize conventionally impossible cryptographic primitives such as unconditionally secure bit-commitment by consuming pre-established correlation between distrustful participants.

The ABC of Deutsch–Hayden Descriptors

open access: yesQuantum Reports, 2021
It has been more than 20 years since Deutsch and Hayden proved the locality of quantum theory, using the Heisenberg picture of quantum computational networks. Of course, locality holds even in the face of entanglement and Bell’s theorem.

Superdense Coding with Uniformly Accelerated Particle [PDF]

open access: yesInternational Journal of Theoretical Physics, 2016
We study superdense coding with uniformly accelerated particle in single mode approximation and beyond single mode approximation. We use four different functions, the capacity of superdense coding, negativity, discord and the probability of success for evaluating the final results. In single mode approximation, all the four functions behave as expected,

Application of Quantum Process Calculus to Higher Dimensional Quantum Protocols [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We describe the use of quantum process calculus to describe and analyze quantum communication protocols, following the successful field of formal methods from classical computer science.

Superdense coding for V-shaped channel and cylindrical geometry

open access: yesPhysica Scripta, 2023
We have examined the possibility of quantum dense coding for the V-shaped channel and cylindrical geometry of plasmonic waveguides by assuming certain initial states at different dipole-dipole distances.
