Distributed quantum dense coding [PDF]
Physical Review Letters, 2004 We introduce the notion of distributed quantum dense coding, i.e. the generalization of quantum dense coding to more than one sender and more than one receiver.

Improving the Capacity of Quantum Dense Coding and the Fidelity of Quantum Teleportation by Weak Measurement and Measurement Reversal. [PDF]
Entropy (Basel), 2023 A protective scheme of quantum dense coding and quantum teleportation of the X-type initial state is proposed in amplitude damping noisy channel with memory using weak measurement and measurement reversal.

Exclusion Principle for Quantum Dense Coding [PDF]
Physical Review A, 2012 We show that the classical capacity of quantum states, as quantified by its ability to perform dense coding, respects an exclusion principle, for arbitrary pure or mixed three-party states in any dimension.

Deterministic Quantum Dense Coding Based on Non-Maximal Entangled Channel. [PDF]
Entropy (Basel)In quantum communication, the concept of dense coding traditionally relies on maximally entangled states as quantum channels. Recent advancements have expanded this framework to include non-maximally entangled states within the probabilistic dense coding

Deterministic Quantum Dense Coding Networks [PDF]
Physics Letters A, 2018 We consider the scenario of deterministic classical information transmission between multiple senders and a single receiver, when they a priori share a multipartite quantum state -- an attempt towards building a deterministic dense coding network ...

Dense coding with multipartite quantum states [PDF]
International Journal of Quantum Information, 2005 We consider generalisations of the dense coding protocol with an arbitrary number of senders and either one or two receivers, sharing a multiparty quantum state, and using a noiseless channel.

Quantum dense coding scheme via cavity decay [PDF]
Journal of Modern Optics, 2006 We investigate a secure scheme for implementing quantum dense coding via cavity decay and liner optics devices. Our scheme combines two distinct advantages: atomic qubit sevres as stationary bit and photonic qubit as flying bit, thus it is suitable for ...

Quantum parallel dense coding of optical images [PDF]
Journal of Modern Optics, 2005 We propose quantum dense coding protocol for optical images. This protocol extends the earlier proposed dense coding scheme for continuous variables [S.L.Braunstein and H.J.Kimble, Phys.Rev.A 61, 042302 (2000)] to an essentially multimode in space and ...
