Detecting positive quantum capacities of quantum channels [PDF]
npj Quantum Information, 2022 AbstractDetermining whether a noisy quantum channel can be used to reliably transmit quantum information is a challenging problem in quantum information theory. This is because it requires computation of the channel’s coherent information for an unbounded number of copies of the channel.

Algorithmic superactivation of asymptotic quantum capacity of zero-capacity quantum channels [PDF]
Information Sciences, 2013 The superactivation of zero-capacity quantum channels makes it possible to use two zero-capacity quantum channels with a positive joint capacity for their output. Currently, we have no theoretical background to describe all possible combinations of superactive zero-capacity channels; hence, there may be many other possible combinations. In practice, to

Maximal Privacy Without Coherence [PDF]
, 2014 Privacy lies at the fundament of quantum mechanics. A coherently transmitted quantum state is inherently private. Remarkably, coherent quantum communication is not a prerequisite for privacy: there are quantum channels that are too noisy to transmit any ...

Strong converse for the quantum capacity of the erasure channel for almost all codes [PDF]
, 2014 A strong converse theorem for channel capacity establishes that the error probability in any communication scheme for a given channel necessarily tends to one if the rate of communication exceeds the channel's capacity.

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.

Entangled inputs cannot make imperfect quantum channels perfect [PDF]
, 2011 Entangled inputs can enhance the capacity of quantum channels, this being one of the consequences of the celebrated result showing the non-additivity of several quantities relevant for quantum information science.
