On the Classical Capacity of General Quantum Gaussian Measurement [PDF]
Entropy, 2021 In this paper, we consider the classical capacity problem for Gaussian measurement channels. We establish Gaussianity of the average state of the optimal ensemble in the general case and discuss the Hypothesis of Gaussian Maximizers concerning the ...

On the classical capacity of quantum Gaussian channels [PDF]
Physica Scripta, 2011 The set of quantum Gaussian channels acting on one bosonic mode can be classified according to the action of the group of Gaussian unitaries. We look for bounds on the classical capacity for channels belonging to such a classification.

Classical capacity of Gaussian thermal memory channels [PDF]
Physical Review A, 2014 The classical capacity of phase-invariant Gaussian channels has been recently determined under the assumption that such channels are memoryless. In this work we generalize this result by deriving the classical capacity of a model of quantum memory ...

Engineering Classical Capacity of Generalized Pauli Channels with Admissible Memory Kernels [PDF]
Entropy, 2021 In this paper, we analyze the classical capacity of the generalized Pauli channels generated via memory kernel master equations. For suitable engineering of the kernel parameters, evolution with non-local noise effects can produce dynamical maps with a ...

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.

Superadditivity of the Classical Capacity with Limited Entanglement Assistance [PDF]
Physical Review Letters, 2017 Finding the optimal encoding strategies can be challenging for communication using quantum channels, as classical and quantum capacities may be superadditive.

Entropy Bound for the Classical Capacity of a Quantum Channel Assisted by Classical Feedback [PDF]
2019 IEEE International Symposium on Information Theory (ISIT), 2019 We prove that the classical capacity of an arbitrary quantum channel assisted by a free classical feedback channel is bounded from above by the maximum average output entropy of the quantum channel.

Classical capacity per unit cost for quantum channels [PDF]
, 2017 In most communication scenarios, sending a symbol encoded in a quantum state requires spending resources such as energy, which can be quantified by a cost of communication.
