Classical Capacity of Classical-Quantum Arbitrarily Varying Channels

IEEE Transactions on Information Theory, 2007
We prove that the average error classical capacity C(W) of a classicalquantum arbitrarily varying channel (cq-AVC) W equals 0 or else the random code capacity C (Ahlswede's dichotomy).

The Classical Capacity of a Quantum Erasure Queue-Channel

International Workshop on Signal Processing Advances in Wireless Communications, 2019
We consider a setting where a stream of qubits is processed sequentially. We derive fundamental limits on the rate at which classical information can be transmitted using qubits that decohere as they wait to be processed.

Classical information capacity of a quantum channel

Physical Review A, 1996
We consider the transmission of classical information over a quantum channel. The channel is defined by an ``alphabet'' of quantum states, e.g., certain photon polarizations, together with a specified set of probabilities with which these states must be sent.

Classical Energy and Capacity

1984
Consider a distribution of positive and negative electric charges on ℝ3 and the electrostatic potential induced by this charge. By definition of a conductor, if A is a connected conducting body in ℝ3, the charge on A distributes itself in such a way that the net effect is that of an all-positive or all-negative charge, and the distribution on A is in ...

Classical capacity of averaged quantum channels

2008 IEEE International Symposium on Information Theory, 2008
In this paper we extend recent coding results by Datta and Dorlas on classical capacity of averaged quantum channels with finitely many memoryless branches to arbitrary number of branches. Only assumption in our approach is that the channel satisfies some weak measurability properties.

Classical capacity of free-space optical communication

Quantum Information and Computation, 2004
The classical-information capacity of lossy bosonic channels is studied, with emphasis on the far-field free space channel.

Classical Capacities of Bosonic Channels

2011
Ubiquitous, reliable, high data rate communication – carried by electromagnetic waves at microwave to optical frequencies – is an essential ingredient of our technological age. Information theory seeks to delineate the ultimate limits on reliable communication that arise from the presence of noise and other disturbances, and to establish means by which

Classical capacities of compound quantum channels

2008 IEEE Information Theory Workshop, 2008
We determine the capacity of compound classical quantum channels. The capacity result for compound channels demonstrates, as in the classical setting, the existence of reliable universal classical-quantum codes in scenarios where the only a priori information about the channel used for the transmission of information is that it belongs to a given set ...

Estimation of the Computation Capacity of Classical Computers

Technical Physics Letters, 2005
Calculations performed by a classical (irreversible) computer are described in terms of the Landauer model representing an ensemble of particles in a potential well with two minima separated by a barrier. Evaluation of the computation capacity of a classical computer under the assumption that the switching rate of such devices is exponentially ...

Capacities of Gaussian classical-quantum channels

2013 IEEE International Symposium on Information Theory, 2013
In the present paper we introduce and study Bosonic Gaussian classical-quantum (c-q) channels; the embedding of the classical input into quantum is always possible and therefore the classical entanglement-assisted capacity Cea under appropriate input constraint is well defined.
