Virtually all of today's information technology is based on the manipulation of classical bits. Quantum systems offer the potential of a much more powerful computing technology, however. In their Perspective, [Bennett and Shor][1] discuss an important aspect of quantum computing--the theoretical capacity of a quantum information channel.

Experimental quantum key distribution beyond the repeaterless secret key capacity
Nature Photonics, 2019Quantum communications promise to revolutionize the way information is exchanged and protected. Unlike their classical counterpart, they are based on dim optical pulses that cannot be amplified by conventional optical repeaters.

Abstract A brief general review is presented of the theory of information transmission capacities of quantum communication channels, which is a development of the classical Shannon theory. Unlike a classical communication channel, a quantum channel is characterised by a whole set of different capacities, which depend on the type of ...

We discuss in this chapter the following topics in quantum information: (1) the channel capacity for quantum communication processes by applying the quantum mutual entropy introduced in Chap. 7, (2) formulations of quantum analogues of McMillan’s theorem and coding type theorem for entanglement transmission.

Conference on Lasers and Electro-Optics 2012, 2012
Channel capacities measure the ultimate communication abilities of noisy channels. I discuss capacities for optical channels with Gaussian noise and show the capacity for quantum information has surprising aspects that could be probed experimentally.

On Entangled Quantum Capacity [PDF]
The pure quantum entanglement is generalized to the case of mixed compoundstates to include the classical-quantum encoding as a particular case. The mutual information of the entangled states leads to a different type of entropy which doubles the von Neumann entropy for a given state and is the true quantum entropy.

Quantum Capacity of Noisy Quantum Channel
1997In quantum communication theory, the quantum mutual entropy [4] is an important tool to analyse the efficiency of information transmission. It is the amount of information correctly transmitted from an input system to an output system through a quantum channel. The supremum of the quantum mutual entropy over a certain set of states with a fixed quantum
