Unbounded number of channel uses may be required to detect quantum capacity [PDF]
Nature Communications, 2014 Transmitting data reliably over noisy communication channels is one of the most important applications of information theory, and is well understood for channels modelled by classical physics.

Capacity of trace decreasing quantum operations and superadditivity of coherent information for a generalized erasure channel [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 Losses in quantum communication lines severely affect the rates of reliable information transmission and are usually considered to be state-independent.

“Pretty Strong” Converse for the Quantum Capacity of Degradable Channels [PDF]
IEEE Transactions on Information Theory, 2013 We exhibit a possible road toward a strong converse for the quantum capacity of degradable channels. In particular, we show that all degradable channels obey what we call a “pretty strong” converse: when the code rate increases above the quantum capacity,

Entanglement-assisted capacity regions and protocol designs for quantum multiple-access channels [PDF]
npj Quantum Information, 2021 We solve the entanglement-assisted (EA) classical capacity region of quantum multiple-access channels (MACs) with an arbitrary number of senders. As an example, we consider the bosonic thermal-loss MAC and solve the one-shot capacity region enabled by an

Capacities of the covariant Pauli channel [PDF]
Phys. Rev. A 106, 062408 (2022), 2022 We study the four well-known capacities of a two-parameter family of qubit Pauli channels. These are the channels which are covariant under the SO(2) group and contain the depolarizing channel as a special case. We find exact expressions for the classical capacity and entanglement assisted capacities, and analytically determine the regions where the ...

Relaxation dynamics of meso-reservoirs
New Journal of Physics, 2014 We study the phenomenology of maximum-entropy meso-reservoirs, where we assume that their local thermal equilibrium state changes consistently with the heat transferred between the meso-reservoirs.
