Quantum interference channels [PDF]
2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011 10 pages, 2 figures, submitted to the 2011 Allerton Conference on Communication, Control, and Computing; v3 has a proof for a two-sender quantum simultaneous decoder and as a result, we get the capacity for channels with strong ...

Notation for general quantum teleportation [PDF]
, 2001 A new notation for the quantum teleportation of finite dimensional quantum state through a generally entangled quantum channel is introduced. For a given quantum channel an explict mathematical criterion that governs the faithful teleportation is ...

Asymptotics of quantum channels
Journal of Physics A: Mathematical and Theoretical, 2023 Abstract We discuss several aspects concerning the asymptotic dynamics of discrete-time semigroups associated with a quantum channel. By using an explicit expression of the asymptotic map, which describes the action of the quantum channel on its attractor manifold, we investigate the role of permutations in the asymptotic dynamics.

Trade-off coding for universal qudit cloners motivated by the Unruh effect [PDF]
, 2011 A "triple trade-off" capacity region of a noisy quantum channel provides a more complete description of its capabilities than does a single capacity formula.

The capacity of black holes to transmit quantum information [PDF]
, 2014 We study the properties of the quantum information transmission channel that emerges from the quantum dynamics of particles interacting with a black hole horizon.

Quantum channel marginal problem
Physical Review Research, 2022 Given a set of local dynamics, are they compatible with a global dynamics? We systematically formulate these questions as quantum channel marginal problems. These problems are strongly connected to the generalization of the no-signaling conditions to quantized inputs and outputs and can be understood as a general toolkit to study notions of quantum ...

Programmability of covariant quantum channels [PDF]
Quantum, 2021 A programmable quantum processor uses the states of a program register to specify one element of a set of quantum channels which is applied to an input register. It is well-known that such a device is impossible with a finite-dimensional program register for any set that contains infinitely many unitary quantum channels (Nielsen and Chuang's No ...
