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

Quantum coherence is a fundamental property of quantum systems, separating quantum
from classical physics. Recently, there has been significant interest in the characterization of …

We develop a resource theory for continuous-variable systems grounded on operations
routinely available within current quantum technologies. In particular, the set of free …

We establish the nonclassicality of continuous-variable states as a resource for quantum
metrology. Based on the quantum Fisher information of multimode quadratures, we …

Genuinely quantum states of a harmonic oscillator may be distinguished from their classical
counterparts by the Glauber-Sudarshan P representation—a state lacking a positive P …

The superposition principle lies at the heart of many nonclassical properties of quantum
mechanics. Motivated by this, we introduce a rigorous resource theory framework for the …

The existence of fundamentally identical particles represents a foundational distinction
between classical and quantum mechanics. Because of their exchange symmetry, identical …

We develop a general framework to assess capabilities and limitations of the Gaussian
toolbox in continuous-variable quantum information theory. Our framework allows us to …

When two qubits are prepared in a mixture of two Bell states and exposed to local
transmission channels, the dynamics of steerability, Bell nonlocality, and average steered …

In this review, the authors introduce the notion of quantum nonclassicality of light and the
role of nonclassicality in optical quantum metrology. The first part of this paper focuses on …
