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 …

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 …

In this work, we address fundamental limitations of quantum teleportation—the process of
transferring quantum information using classical communication and preshared …

Entanglement quantification aims to assess the value of quantum states for quantum
information processing tasks. A closely related problem is state convertibility, asking whether …

Determining whether a given state can be transformed into a target state using free
operations is one of the fundamental questions in the study of resource theories. Free …

Quantum entanglement of pure states is usually quantified via the entanglement entropy, the
von Neumann entropy of the reduced state. Entanglement entropy is closely related to …

I show that nondecreasing entropy provides a necessary and sufficient condition to convert
the state of a physical system into a different state by a reversible transformation that acts on …

Temperature is usually defined for physical systems at thermal equilibrium. Nevertheless
one may wonder if it would be possible to attribute a meaningful notion of temperature to an …

Quantum resource manipulation may include an ancillary state called a catalyst, which aids
the transformation while restoring its original form at the end, and characterizing the …

Quantum coherence is one of the fundamental aspects distinguishing classical and quantum
theories. Coherence between different energy eigenstates is particularly important, as it …
