The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

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

We introduce a rigorous framework for the quantification of coherence and identify intuitive
and easily computable measures of coherence. We achieve this by adopting the viewpoint …

We establish an operational theory of coherence (or of superposition) in quantum systems,
by focusing on the optimal rate of performance of certain tasks. Namely, we introduce the …

Quantifying coherence is an essential endeavor for both quantum foundations and quantum
technologies. Here, the robustness of coherence is defined and proven to be a full …

Recent studies have developed fundamental limitations on nanoscale thermodynamics, in
terms of a set of independent free energy relations. Here we show that free energy relations …

The ideas of thermodynamics have proved fruitful in the setting of quantum information
theory, in particular the notion that when the allowed transformations of a system are …

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 …

Because of conservation of energy we cannot directly turn a quantum system with a definite
energy into a superposition of different energies. However, if we have access to an …

Considerable work has recently been directed toward develo** resource theories of
quantum coherence. In this Letter, we establish a criterion of physical consistency for any …
