A fully-connected three-user quantum hyperentangled network
Quantum Frontiers, 2023 Exploiting the fantastic features of quantum mechanics, a hyperentangled quantum network encoded in multiple degree of freedoms (DOF), e.g., polarization and orbital angular momentum DOFs, can encode more qubits per transmitted photon and offers a ...

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.

Entanglement-assisted capacity regions and protocol designs for quantum multiple-access channels
npj Quantum Information, 2021 We solve the entanglement-assisted (EA) classical capacity region of quantum multiple-access channels (MACs) with an arbitrary number of senders. As an example, we consider the bosonic thermal-loss MAC and solve the one-shot capacity region enabled by an

Coherent Communication with Continuous Quantum Variables [PDF]
, 2006 The coherent bit (cobit) channel is a resource intermediate between classical and quantum communication. It produces coherent versions of teleportation and superdense coding.

QUANTUM KEY DISTRIBUTION USING SUPER DENSE CODING [PDF]
Journal of Mechanics of Continua and Mathematical SciencesBuilt based on the fundamental principles of quantum mechanics, Quantum Key Distribution (QKD) enables secure communication for distant parties. Entanglement-based protocols are a type of QKD protocol that uses the phenomenon of entanglement for ...

Negative entropy and information in quantum mechanics [PDF]
, 1997 A framework for a quantum mechanical information theory is introduced that is based entirely on density operators, and gives rise to a unified description of classical correlation and quantum entanglement. Unlike in classical (Shannon) information theory,

More Communication with Less Entanglement
, 2015 We exhibit the intriguing phenomena of "Less is More" using a set of multipartite entangled states. We consider the quantum communication protocols for the {\em exact} teleportation, superdense coding, and quantum key distribution. We find that sometimes

Catalytic quantum error correction [PDF]
, 2006 We develop the theory of entanglement-assisted quantum error correcting (EAQEC) codes, a generalization of the stabilizer formalism to the setting in which the sender and receiver have access to pre-shared entanglement.
