SuperDense Coding Step by Step

Lecture Notes in Networks and Systems, 2019
Scholars of quantum computing all become familiar with Alice and Bob when learning about superdense coding and entanglement. However, in every research book and video that we found, the assumption is made that the student will automatically understand how those two classical bits at the end come to their values when they started as two qubits.

Quantum Control Mechanisms of Superdense Coding

2022 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF), 2022
Control frames in quantum schemes for superdense coding are considered. A generalized solution is proposed for quantum control schemes that allow long (n-bit) sequences to be transmitted using a single qubit.

Teleportation, Superdense Coding and Bell’s Inequality

Quantum Computing: An Applied Approach, 2019
Two of the most fascinating quantum circuits enable us to transmit information in ways that are not possible in the classical regime. In this chapter, we will learn how to build these two circuits. We will then examine a foundational advance in quantum mechanics, the Bell Inequality.

Superdense Coding Through Repeaterless Hybrid Network of Depolarizing Quantum Communication Channels

IEEE International Conference on Electronics, Computing and Communication Technologies, 2021
Superdense coding is a fundamental protocol in quantum communication, which enables us to send two bits of information by the transmission of just a single qubit.

Modified quantum superdense coding for distributed communications

International Journal of Communication Systems, 2016
SUMMARYThe efficiency of medium access control strongly influences the performance of distributed wireless networks. Collisions in the channel and unused timeslots result in poor performance. On the other hand, quantum superdense coding proved that entanglement‐assisted quantum communications can improve the data transmission rates compared with ...

Quantum superdense coding based on hyperentanglement

Chinese Physics B, 2012
We present a scheme for quantum superdense coding with hyperentanglement, in which the sender can transfer four bits of classical information by sending only one photon. The important device in the scheme is the hyperentangled Bell-state analyzer in both polarization and frequency degrees of freedom, which is also constructed in the paper by using a ...

Superdense coding with single-particle entanglement [PDF]

Journal of Russian Laser Research, 2009
Recent work has explored the idea that nonlocality or entanglement involving a single particle should be taken seriously and has real measurable consequences. Theoretical and experimental schemes have shown, for example, that single-particle states can violate Bell’s inequalities.

Quantum Authentication Protocol for Secure Quantum Superdense Coding

SoutheastCon
In quantum information theory, superdense coding allows two network entities to exchange two classical bits via a quantum channel using a single quantum bit (qubit) transmission, provided they have pre-shared an entangled qubit.

Deterministic mediated superdense coding with linear optics

Physics Letters A, 2016
We present a scheme of deterministic mediated superdense coding of entangled photon states employing only linear-optics elements. Ideally, we are able to deterministically transfer four messages by manipulating just one of the photons. Two degrees of freedom, polarization and spatial, are used.
