Enhanced Superdense Coding over Correlated Amplitude Damping Channel [PDF]
Entropy, 2019 Quantum channels with correlated effects are realistic scenarios for the study of noisy quantum communication when the channels are consecutively used. In this paper, superdense coding is reexamined under a correlated amplitude damping (CAD) channel. Two

Dual Quantum Zeno Superdense Coding. [PDF]
Sci Rep, 2019 AbstractQuantum superdense coding enables a sender to encode a two-bit classical message in one qubit using the preshared entanglement. In this paper, we develop a superdense coding protocol using a dual quantum Zeno (DQZ) gate to take the full advantage of quantum superdense coding from the complete Bell-state analysis.

Towards symmetric scheme for superdense coding between multiparties [PDF]
Physical Review A, 2002 Recently Liu, Long, Tong and Li [Phys. Rev. A 65, 022304 (2002)] have proposed a scheme for superdense coding between multiparties. This scheme seems to be highly asymmetric in the sense that only one sender effectively exploits entanglement.

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 ...

Classical information capacity of superdense coding [PDF]
Physical Review A, 2015 Classical communication through quantum channels may be enhanced by sharing entanglement. Superdense coding allows the encoding, and transmission, of up to two classical bits of information in a single qubit.

Rigidity of Superdense Coding [PDF]
ACM Transactions on Quantum Computing, 2023 The famous superdense coding protocol of Bennett and Wiesner demonstrates that it is possible to communicate two bits of classical information by sending only one qubit and using a shared EPR pair. Our first result is that an arbitrary protocol for achieving this task (where there are no assumptions on the sender’s encoding operations or ...

Superdense coding of quantum states [PDF]
Physical Review Letters, 2004 We describe a method to non-obliviously communicate a 2l-qubit quantum state by physically transmitting l+o(l) qubits of communication, and by consuming l ebits of entanglement and some shared random bits.

Perfect Teleportation and Superdense Coding With W-States [PDF]
, 2006 True tripartite entanglement of the state of a system of three qubits can be classified on the basis of stochastic local operations and classical communications (SLOCC). Such states can be classified in two categories: GHZ states and W-states.
