Mutually Unbiased Measurements, Hadamard Matrices, and Superdense Coding [PDF]
IEEE Transactions on Information Theory, 2022 Mutually unbiased bases (MUBs) are highly symmetric bases on complex Hilbert spaces, and the corresponding rank-1 projective measurements are ubiquitous in quantum information theory. In this work, we study a recently introduced generalization of MUBs called mutually unbiased measurements (MUMs).

Optimal Superdense Coding Capacity in the Non-Markovian Regime [PDF]
Journal of Physics A: Mathematical and TheoreticalAbstract Superdense coding (SDC) is a significant technique widely used in quantum information processing. Indeed, it consists of sending two bits of classical information using a single qubit, leading to faster and more efficient quantum communication. In this paper, we propose a model to evaluate the effect of backflow information in a

A-unital Operations and Quantum Conditional Entropy [PDF]
Quantum, 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 Using Bragg Diffracted Hyperentangled Atoms [PDF]
IEEE Journal on Selected Areas in CommunicationsSuperdense coding (SDC) is a popular protocol demonstrating the potential of using quantum mechanics to transfer data, where The sender (Alice) can transfer 2 bits of classical information over a single qubit. We present a scheme for quantum superdense coding through Bragg diffracted hyperentangled atoms generated using cavity quantum electrodynamics ...

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

Classical hypercorrelation and wave-optics analogy of quantum superdense coding. [PDF]
Sci Rep, 2015 AbstractWe report the first experimental realization of classical hypercorrelation, correlated simultaneously in every degree of freedom (DOF), from observing a Bell-type inequality violation in each DOF: polarization and orbital angular momentum (OAM).

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

Challenges of Superdense Coding with Accelerated Fermions [PDF]
Universal Journal of Physics and Application, 2017 Two particles, even being far from each other have quantum correlation as a result of the existence of entanglement between them. Therefore, information can be shared by entangled particles, sitting in separate places. Superdense coding is one of the quantum protocols that rely on entanglement.

Superdense Coding Interleaved with Forward Error Correction
Quantum Measurements and Quantum Metrology, 2016 AbstractSuperdense coding promises increased classical capacity and communication security but this advantage may be undermined by noise in the quantum channel. We present a numerical study of how forward error correction (FEC) applied to the encoded classical message can be used to mitigate against quantum channel noise. By studying the bit error rate
