Geometric approach to entanglement quantification with polynomial measures

2016 · Physical Review A

We show that the quantification of entanglement of any rank-2 state with any polynomial entanglement measure can be recast as a geometric problem on the corresponding Bloch sphere. This approach provides insight into the properties …

Quantum-enhanced measurements without entanglement

2018 · Reviews of Modern Physics

Entangled quantum states can enhance measurement precision. But quantum mechanics harbors other possibilities for enhancing precision, including some that have nothing to do with entanglement. This review surveys various strategies with unentangled probes by which …

Certification and Quantification of Multilevel Quantum Coherence

2018 · Physical Review X

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within a resource-theoretic …
