Dense Quantum Coding and a Lower Bound for 1-way Quantum Automata [PDF]
Proceedings of the thirty-first annual ACM symposium on Theory of Computing, 1998 We consider the possibility of encoding m classical bits into much fewer n quantum bits so that an arbitrary bit from the original m bits can be recovered with a good probability, and we show that non-trivial quantum encodings exist that have no ...

Complete multiple round quantum dense coding with quantum logical network
Chinese Science Bulletin, 2007 We present a complete multiple round quantum dense coding scheme for improving the source capacity of that introduced recently by Zhang et al. The receiver resorts to two qubits for storing the four local unitary operations in each round.

Advances in Quantum Dense Coding [PDF]
Advanced Quantum Technologies, 2019 Abstract Quantum dense coding is one of the most important protocols in quantum communication. It derives from the idea of using quantum resources to boost the communication capacity and now serves as a key primitive across a variety of quantum information protocols.

Results in Physics, 2022 By using the non-Markovian Quantum State Diffusion method, the non-Markovian dynamics of entanglement, quantum dense coding and quantum teleportation in the spin chain system with Kaplan-Shekhtman-Entin-wohlman-Aharony interactions and Dzyaloshinskii ...

IEEE Access, 2023 Based on the two-photon six-qubit hyperentangled Bell states and hyper-coding, a new high-capacity quantum privacy comparison (QPC) protocol is proposed to realize a high utilization of quantum resources.

Atmospheric implementation of superdense coding quantum algorithm
Physics of Complex Systems, 2022 We consider the properties of a quantum communication channel in open space using the superdense coding algorithm as an example. We studied the theoretical model of the installation that implements this algorithm, and identified the main factors ...

Quantum-Classical Hybrid Systems and their Quasifree Transformations [PDF]
Quantum, 2023 We study continuous variable systems, in which quantum and classical degrees of freedom are combined and treated on the same footing. Thus all systems, including the inputs or outputs to a channel, may be quantum-classical hybrids.

Dense quantum coding and quantum finite automata [PDF]
Journal of the ACM, 2002 We consider the possibility of encoding m classical bits into many fewer n quantum bits (qubits) so that an arbitrary bit from the original m bits can be recovered with good probability.
