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 study quantum frequency estimation for N qubits subjected to independent Markovian
noise, via strategies based on time-continuous monitoring of the environment. Both physical …

Coherent superposition is a key feature of quantum mechanics that underlies the advantage
of quantum technologies over their classical counterparts. Recently, coherence has been …

We show that both the classical as well as the quantum definitions of the Fisher information
faithfully identify resourceful quantum states in general quantum resource theories, in the …

The ability of quantum states to be in superposition is one of the key features that sets them
apart from the classical world. This “coherence” is rigorously quantified by resource theories …

Quantum coherence, present whenever a quantum system exists in a superposition of
multiple classically distinct states, marks one of the fundamental departures from classical …

Quantum coherence is a basic concept in quantum mechanics, representing one of the most
fundamental characteristics that distinguishes quantum mechanics from classical physics …

Coherence is a defining property of quantum theory that accounts for quantum advantage in
many quantum information tasks. Although many coherence quantifiers were introduced in …

The recently established resource theory of quantum coherence allows for a quantitative
understanding of the superposition principle, with applications reaching from quantum …

Since both coherence and quantum correlations arise from the superposition principle and
can be regarded as resources in quantum information tasks, it is of significance to …
