Dual Quantum Zeno Superdense Coding. [PDF]
Sci Rep, 2019 Quantum 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 ...

Classical information capacity of superdense coding [PDF]
Physical Review A, 2001 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.

Role of complementarity in superdense coding [PDF]
Physical Review A, 2013 The complementarity of two observables is often captured in uncertainty relations, which quantify an inevitable tradeoff in knowledge. Here we study complementarity in the context of an information processing task: we link the complementarity of two ...

ENTANGLEMENT AND SUPERDENSE CODING WITH LINEAR OPTICS [PDF]
International Journal of Quantum Information, 2011 We discuss a scheme for a full superdense coding of entangled photon states employing only linear-optics elements. By using the mixed basis consisting of four states that are unambiguously distinguishable by a standard and polarizing beam splitters we ...

Mutually Unbiased Measurements, Hadamard Matrices, and Superdense Coding [PDF]
IEEE Transactions on Information Theory, 2022 Mutually unbiased bases (MUBs) are highly symmetric bases on complex Hilbert spaces, and the corresponding rank-1 projective measurements are ubiquitous in quantum information theory.

Superdense Coding Interleaved with Forward Error Correction [PDF]
Quantum Measurements and Quantum Metrology, 2016 Superdense coding promises increased classical capacity and communication security but this advantage may be undermined by noise in the quantum channel.
