Quantum secure direct communication network with superdense coding and decoy photons [PDF]

, 2007
A quantum secure direct communication network scheme is proposed with quantum superdense coding and decoy photons. The servers on a passive optical network prepare and measure the quantum signal, i.e., a sequence of the $d$-dimensional Bell states. After

Classical hypercorrelation and wave-optics analogy of quantum superdense coding. [PDF]

Sci Rep, 2015
AbstractWe report the first experimental realization of classical hypercorrelation, correlated simultaneously in every degree of freedom (DOF), from observing a Bell-type inequality violation in each DOF: polarization and orbital angular momentum (OAM).

Perfect Teleportation, Quantum state sharing and Superdense Coding through a Genuinely Entangled Five-qubit State [PDF]

, 2008
We investigate the usefulness of a recently introduced five qubit state by Brown $\it et al. \normalfont$ \cite{Brown} for quantum teleportation, quantum state sharing and superdense coding.

The states of W-class as shared resources for perfect teleportation and superdense coding [PDF]

, 2007
As we know, the states of triqubit systems have two important classes: GHZ-class and W-class. In this paper, the states of W-class are considered for teleportation and superdense coding, and are generalized to multi-particle systems.

Beating the channel capacity limit for linear photonic superdense coding [PDF]

, 2010
Dense coding is arguably the protocol that launched the field of quantum communication. Today, however, more than a decade after its initial experimental realization, the channel capacity remains fundamentally limited as conceived for photons using ...

Challenges of Superdense Coding with Accelerated Fermions [PDF]

Universal Journal of Physics and Application, 2017
Two particles, even being far from each other have quantum correlation as a result of the existence of entanglement between them. Therefore, information can be shared by entangled particles, sitting in separate places. Superdense coding is one of the quantum protocols that rely on entanglement.

Superdense coding for quantum networking environments

Advances in Photonics of Quantum Computing, Memory, and Communication XI, 2018
Quantum networks provide a versatile infrastructure for communication, computing, and sensing with quantum information. Novel sources and detectors for transmitting and receiving quantum states are critical elements in the development and eventual deployment of robust quantum networks. Alongside performance, the compatibility of quantum network devices

Superdense coding using the quantum superposition principle [PDF]

, 2009
By sending a classical two-level system, one can transfer information about only \emph{two} distinguishable outcomes. Here we show that in quantum mechanics, using both the spin and path degrees of freedom of a spin-1/2 particle, and a Mach-Zehnder type interferometric arrangement with two suitable Stern-Gerlach detectors, it is possible to transfer ...
