Robust quantum metrology with random Majorana constellations
A. Z. Goldberg, J. R. Hervas, Ángel S Sanz +8
Even the most classical states are still governed by quantum theory. A number of physical systems can be described by their Majorana constellations of points on the surface of a sp…

Taming singularities of the quantum Fisher information
Aaron Z. Goldberg, José L. Romero, Ángel S. Sanz +1
Quantum Fisher information matrices (QFIMs) are fundamental to estimation theory: they encode the ultimate limit for the sensitivity with which a set of parameters can be estimated…
