Secure Quantum Turbo Coded Superdense Coding Scheme

2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018
In this paper we present a novel secure quantum turbo coded (QTC) superdense (SD) coding scheme. We have integrated SD with QTC to benefit from the inherent near optimum performance of turbo codes. We have further incorporated the quantum secure direct communication (QSDC) protocol within the proposed QTC-SD system for the sake of ensuring absolute ...

Superdense Coding and Quantum Teleportation

2006
We are now ready to look at our first protocols for quantum information. In this section, we examine two communication protocols which can be implemented using the tools we have developed in the preceding sections. These protocols are known as superdense coding and quantum teleportation.

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 ...

Quantum–classical hybrid quantum superdense coding

Physica Scripta, 2013
Quantum superdense coding (QSC) is an interesting application of quantum communications. It exploits the special property of quantum entanglement to perform classical communications and results in a spectacular result. In this paper, the density of QSC problem is investigated and a time synchronization mechanism is shown to be helpful for improving the

SuperDense Coding Step by Step

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.
