Quantum superdense coding via cavity-assisted interactions [PDF]

Chinese Physics B, 2009
Quantum superdense coding (QSC) is an example of how entanglement can be used to minimize the number of carriers of classical information. This paper proposes two schemes for implementing QSC by means of cavity assisted interactions with single-photon pulses.

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 via Hot Trapped Ions

Communications in Theoretical Physics, 2004
Superdense coding plays an important role in quantum information and can be performed with trapped ions. By confining the ions in a linear trap or a trap-cavity setup, we propose schemes to implement a reliable superdense coding by means of bichromatic radiation method.

Probabilistic Superdense Coding Based on the Mixed Entangled State [PDF]

2014 Sixth International Conference on Intelligent Human-Machine Systems and Cybernetics, 2014
Ideal dense coding protocols allow one to use prior maximal entanglement to send two bits of classical information by the physical transfer of a single encoded qubit. We investigate the case when the prior entanglement is not maximal and the initial state of the entangled pair of qubits being used for the dense coding is a mixed state.

Quantum Secure Direct Intercommunication with Superdense Coding

2008 International Conference on Security Technology, 2008
A quantum secure direct intercommunication scheme is proposed to exchange directly the communicators' secret messages by making use of swapping entanglement of Bell states. It has great capacity to distribute the secret messages since these messages have been imposed on high-dimensional Bell states via the local unitary operations with superdense ...

The generation of Entangled Qudits and their Application in Probabilistic Superdense Coding

Chinese Physics Letters, 2009
A scheme of the generation of entangled qutrits is presented, and then is generalized to entangled ququads and entangled qudits. With the entangled qutrits, an experimental scheme of probability superdense coding with only linear optical elements is proposed.
