Entanglement Witness Derived from NMR Superdense Coding [PDF]

open access: greenJournal of Physics A: Mathematical and General, 2004
We show that it is possible to transfer two-bit information via encoding a single qubit in a conventional nuclear magnetic resonance (NMR) experiment with two very weakly polarized nuclear spins. Nevertheless, the experiment can not be regarded as a demonstration of superdense coding by means of NMR because it is based on the large number of molecules ...

Superdense Coding with GHZ and Quantum Key Distribution with W in the ZX-calculus [PDF]

open access: diamondElectronic Proceedings in Theoretical Computer Science, 2012
Quantum entanglement is a key resource in many quantum protocols, such as quantum teleportation and quantum cryptography. Yet entanglement makes protocols presented in Dirac notation difficult to verify.

Superdense coding using multipartite states [PDF]

open access: green, 2004
We show that with the fourpartite quantum channel used to teleport an arbitrary two qubit state, we can construct a superdense coding protocol where it is possible to transmit 4 bits of classical information sending only 2 qubits. Alice and Bob initially share a four qubit maximally entangled state and by locally manipulating her two qubits Alice can ...

Integration of a Quantum Voting Scheme into Grayscale Images Using the Novel Enhanced Quantum Representation and Qiskit Framework

open access: yesModelling and Simulation in Engineering, 2022
This paper illustrates the way a proposed quantum voting scheme can be designed in combination with a steganography technique called Least Significant Bit (LSB), by modifying a small number of pixels in multiple grayscale images.

Role of complementarity in superdense coding [PDF]

open access: yesPhysical Review A, 2013
The complementarity of two observables is often captured in uncertainty relations, which quantify an inevitable tradeoff in knowledge. Here we study complementarity in the context of an information processing task: we link the complementarity of two ...

On the Storage–Communication Trade-Off in Graph-Based X-Secure T-Private Linear Computation [PDF]

open access: yesEntropy
The problem of graph-based X-secure T-private linear computation (GXSTPLC) is to allow a user to retrieve a linear combination of K messages from a set of N distributed servers that store the messages in a graph-based fashion, i.e., each message is ...

Hyperdense coding and superadditivity of classical capacities in hypersphere theories

open access: yesNew Journal of Physics, 2015
In quantum superdense coding, two parties previously sharing entanglement can communicate a two bit message by sending a single qubit. We study this feature in the broader framework of general probabilistic theories.

Four-dimensional entanglement distribution over 100 km [PDF]

open access: yesScientific Reports, 2018
High-dimensional quantum entanglement can enrich the functionality of quantum information processing. For example, it can enhance the channel capacity for linear optic superdense coding and decrease the error rate threshold of quantum key distribution ...

Superdense Coding Using Bragg Diffracted Hyperentangled Atoms [PDF]

open access: yesIEEE Journal on Selected Areas in Communications
Superdense 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 ...
