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

Quantum metrology holds the promise of an early practical application of quantum
technologies, in which measurements of physical quantities can be made with much greater …

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 …

Quantum coherence is the key resource for quantum technology, with applications in
quantum optics, information processing, metrology, and cryptography. Yet, there is no …

We investigate the performance of entangled coherent states for quantum-enhanced phase
estimation. An exact analytical expression of quantum Fisher information is derived to show …

Quantum mechanics predicts that measurements of incompatible observables carry a
minimum uncertainty which is independent of technical deficiencies of the measurement …

We present several entanglement criteria in terms of the quantum Fisher information that
help to relate various forms of multipartite entanglement to the sensitivity of phase …

We show that quantum Fisher information provides a sufficient condition to recognize
multiparticle entanglement in an N qubit state. The same criterion gives a necessary and …

Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

Noether's theorem is a fundamental result in physics stating that every symmetry of the
dynamics implies a conservation law. It is, however, deficient in several respects: for one, it …
