A quantum communication channel can be put to many uses: it can transmit classical information, private classical information, or quantum information. It can be used alone, with shared entanglement, or together with other channels. For each of these settings there is a capacity that quantifies a channel's potential for communication. In this short review, I summarize what is known about the various capacities of a quantum channel, including a discussion of the relevant additivity questions. I… Expand
A Survey on Quantum Channel Capacities
The properties of the quantum communication channel, the various capacity measures and the fundamental differences between the classical and quantum channels are reviewed. Expand
Quantum teleportation over hyper entangled states
This work derives the maximum coherent information of this virtual quantum channel under noisy classical channel existing between the end users by treating teleportation as a transfer of qubits between end users sharing avirtual quantum channel. Expand
Average output entropy for quantum channels
We study the regularized average Renyi output entropy S¯r reg of quantum channels. This quantity gives information about the average noisiness of the channel output arising from a typical, highlyExpand
The Quantum Capacity of a Quantum Channel

Performance analysis of quantum channels
Queueing analysis of both the classical information transmission and quantum information transmission in the quantum channel is presented, and a new queueing model is proposed and investigated and tail distributions of the performance measures are obtained. Expand

Fundamentals of Information Theory
This chapter introduces some elementary concepts regarding information theory, including entropy and other measures of information, and introduces the mathematical formulation of quantum channels, including the Choi-Jamiolkowski isomorphism. Expand
Multidimensional quantum information based on single-photon temporal wavepackets.
We propose a multidimensional quantum information encoding approach based on temporal modulation of single photons, where the Hilbert space can be spanned by an in-principle infinite set ofExpand
CB-norm estimates for maps between noncommutative $L_p$-spaces and quantum channel theory
In the first part of this work we show how certain techniques from quantum information theory can be used in order to obtain very sharp embeddings between noncommutative $L_p$-spaces. Then, we useExpand


Quantum Communication with Zero-Capacity Channels
It is shown theoretically that two quantum channels, each with a transmission capacity of zero, can have a nonzero capacity when used together, implying that the quantum capacity does not completely specify a channel's ability to transmit quantum information. Expand

Motivated by the work of Schumacher and Westmoreland on quantum privacy and quantum coherence, parallels between private classical information and quantum information are exploited to obtain an expression for the capacity of a quantum channel for generating pure bipartite entanglement. Expand
The Capacity of a Quantum Channel for Simultaneous Transmission of Classical and Quantum Information
An expression is derived characterizing the set of admissible rate pairs for simultaneous transmission of classical and quantum information over a given quantum channel, generalizing both theExpand
Can nonprivate channels transmit quantum information?
Strong evidence is found that there are pairs of quantum channels with little or no capacity for private communication that, when used together, can transmit far more quantum information than the sum of their individual private capacities. Expand

A Decoupling Approach to the Quantum Capacity
A short proof that the coherent information is an achievable rate for the transmission of quantum information through a noisy quantum channel and a modification yielding unitarily invariant ensembles of maximally entangled codes is given. Expand

Additivity of the classical capacity of entanglement-breaking quantum channels

Private capacity of quantum channels is not additive.
It is concluded for the first time that the classical private capacity is nonadditive: in this construction even the quantum capacity of the tensor product of two channels can be greater than the sum of their individual classical private capacities. Expand
