Fundamental limitations on distillation of quantum channel resources
Quantum channels underlie the dynamics of quantum systems, but in many practical settings
it is the channels themselves that require processing. We establish universal limitations on …

Dynamical entanglement
G Gour, CM Scandolo - Physical Review Letters, 2020 - APS
Unlike the entanglement of quantum states, very little is known about the entanglement of
bipartite channels, called dynamical entanglement. Here we work with the partial transpose …

Entanglement of a bipartite channel
G Gour, CM Scandolo - Physical Review A, 2021 - APS
The most general quantum object that can be shared between two distant parties is a
bipartite channel, as it is the basic element to construct all quantum circuits. In general …
