Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

Quantum resource theories (QRTs) offer a highly versatile and powerful framework for
studying different phenomena in quantum physics. From quantum entanglement to quantum …

In 1835, Jacob Berzelius observed a common feature among several chemical reactions:
they all required an additional substance, which remained unchanged in the process. He …

A question that is commonly asked in all areas of physics is how a certain property of a
physical system can be used to achieve useful tasks and how to quantify the amount of such …

The von Neumann entropy is a key quantity in quantum information theory and, roughly
speaking, quantifies the amount of quantum information contained in a state when many …

Compression of a message up to the information it carries is key to many tasks involved in
classical and quantum information theory. Schumacher [B. Schumacher, Phys. Rev. A 51 …

Information-theoretic approaches provide a promising avenue for extending the laws of
thermodynamics to the nanoscale. Here, we provide a general fundamental lower limit, valid …

A capacity of a quantum channel characterizes the limits of reliable communication through
a noisy quantum channel. This fundamental information-theoretic question is very well …

We study the general framework of quantum channel simulation, that is, the ability of a
quantum channel to simulate another one using different classes of codes. First, we show …

Thermodynamics imposes restrictions on what state transformations are possible. In the
macroscopic limit of asymptotically many independent copies of a state—as for instance in …
