Thirty years after it was first proposed, quantum teleportation remains one of the most
important protocols in quantum information and quantum technologies, enabling the …

Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

Quantum teleportation provides a way to transmit unknown quantum states from one
location to another. In the quantum world, multilevel systems which enable high-dimensional …

We provide a complete set of game-theoretic conditions equivalent to the existence of a
transformation from one quantum channel into another one, by means of classically …

Semidefinite programs are convex optimisation problems involving a linear objective
function and a domain of positive semidefinite matrices. Over the last two decades, they …

For any resource theory it is essential to identify tasks for which resource objects offer
advantage over free objects. We show that this identification can always be accomplished …

In space-like separated experiments and other scenarios where multiple parties share a
classical common cause but no cause-effect relations, quantum theory allows a variety of …

We study the protocol of qudit teleportation using quantum systems subjected to several
kinds of noise for arbitrary dimensionality d. We consider four classes of noise: dit-flip, d …

The efficient and reliable certification of quantum states is essential for various quantum
information processing tasks as well as for the general progress on the implementation of …

How to properly certify the quantum function of a quantum process (device) is one of the key
problems in quantum information science, particularly, for a function beyond its classical …
