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 coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

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 …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

Based on the theory of quantum mechanics, intrinsic randomness in measurement
distinguishes quantum effects from classical ones. From the perspective of states, this …

Recent results in quantum information theory characterize quantum coherence in the context
of resource theories. Here, we study the relation between quantum coherence and quantum …

Within the unified framework of exploiting the relative entropy as a distance measure of
quantum correlations, we make explicit the hierarchical structure of quantum coherence …

Quantum coherence is a critical resource for many operational tasks. Understanding how to
quantify and manipulate it also promises to have applications for a diverse set of problems in …

Quantum states may exhibit asymmetry with respect to the action of a given group. Such an
asymmetry of states can be considered a resource in applications such as quantum …
