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.

Nonorthogonal Quantum States Maximize Classical Information Capacity [PDF]
Physical Review Letters, 1997 I demonstrate that, rather unexpectedly, there exist noisy quantum channels for which the optimal classical information transmission rate is achieved only by signaling alphabets consisting of nonorthogonal quantum states.Comment: 5 pages, REVTeX, mild ...

Classical Capacity of A Quantum Multiple Access Channel [PDF]
Physical Review A, 2000 We consider the transmission of classical information over a quantum channel by two senders. The channel capacity region is shown to be a convex hull bound by the Von Neumann entropy and the conditional Von Neumann entropy.

Exceeding classical capacity limit in quantum optical channel [PDF]
Physical Review Letters, 2003 The amount of information transmissible through a communications channel is determined by the noise characteristics of the channel and by the quantities of available transmission resources.

Commitment capacity of classical-quantum channels
2022 IEEE International Symposium on Information Theory (ISIT), 2022 We study commitment scheme for classical-quantum channels. To accomplish this we define various notions of commitment capacity for these channels and prove matching upper and lower bound on it in terms of the conditional entropy. Our achievability (lower bound) proof is quantum generalisation of the work of one of the authors (arXiv:2103.11548) which ...

Quantum Receivers for Entanglement Assisted Classical Optical Communications
IEEE Photonics Journal, 2021 Entanglement assisted (EA) communication represents an interesting alternative to classical communication, in particular in low-brightness and highly noisy regime when it outperforms significantly corresponding classical counterpart in terms of the ...

Regeneration limit of classical Shannon capacity [PDF]
Nature Communications, 2014 Since Shannon derived the seminal formula for the capacity of the additive linear white Gaussian noise channel, it has commonly been interpreted as the ultimate limit of error-free information transmission rate. However, the capacity above the corresponding linear channel limit can be achieved when noise is suppressed using nonlinear elements; that is,
