We generalize alternating optimization algorithms of Blahut-Arimoto type to the quantum setting. In particular, we give iterative algorithms to compute the mutual information of quantum channels, the thermodynamic capacity of quantum channels, the co

Classical Bose–Chaudhuri–Hocquenghem (BCH) codes over finite fields have been studied extensively. One can construct quantum stabilizer codes with good parameters using classical BCH codes. In this paper, our goal is to find such classical BCH co

It is known that the conventional second law of thermodynamics is not applicable to thermodynamic systems when feedback control is applied to such systems. A generalized form of the second law should be introduced in this case, which contains an addi

We show that the max-Rains information of a quantum channel is an efficiently computable, single-letter strong converse upper bound for transmitting quantum information over quantum channels when assisted by positive-partial-transpose (PPT) preservin

This paper focuses on the mutual information and minimum mean-squared error (MMSE) as a function a matrix-valued signal-to-noise ratio (SNR) for a linear Gaussian channel with arbitrary input distribution. As shown by Lamarca, the mutual-information

We consider a model of communication via a fully quantum jammer channel with quantum jammer, quantum sender and quantum receiver, which we dub quantum arbitrarily varying channel (QAVC). Restricting to finite dimensional user and jammer systems, we s

A doubly spatially-correlated multi-cluster scattering Rayleigh MIMO channel with rectangular scattering cluster matrices (under the assumption that the minimum dimension of these matrices is equal to the number of transmit and receive antennas) is c

A one-sided spatially-correlated multi-cluster scattering Rayleigh MIMO channel is considered in this work and its outage probability is derived in an analytic form based on Meijer function determinants. First, the spatially-uncorrelated case is addr

We consider the problem of transmitting classical information over a time-invariant channel with memory. A popular class of time-invariant channels with memory are finite-state-machine channels, where a classical state evolves over time and governs t

In this paper, quaternary quantum Reed-Muller code construction with Gray map is investigated. Using the proposed approach, generated quaternary quantum code can be gained with short length of codeword. These quantum codes are simple for implementati
