The quantum sky of Majorana stars
L. L. Sanchez-Soto, A. B. Klimov, A. Z. Goldberg +1
Majorana stars, the spin coherent states that are orthogonal to a spin- state, offer an elegant method to visualize quantum states. This representation offers deep insights…
Quantum multiphase estimation
Marco Barbieri, Ilaria Gianani, Aaron Z. Goldberg +1
Quantum phase estimation is fundamental to advancing quantum science and technology. While much of the research has concentrated on estimating a single phase, the simultaneous esti…
Optimizing measurement tradeoffs in multiparameter spatial superresolution
J. Řeháček, J. L. Romero, A. Z. Goldberg +2
The quantum Cramér-Rao bound for the joint estimation of the centroid and the separation between two incoherent point sources cannot be saturated. As such, the optimal measurements…
Multipoles from Majorana constellations
J. L. Romero, A. B. Klimov, A. Z. Goldberg +2
Majorana stars, the spin coherent states that are orthogonal to a spin- state, offer an elegant method to visualize quantum states, disclosing their intrinsic symmetries. T…
Sensing rotations with multiplane light conversion
M. Eriksson, A. Z. Goldberg, M. Hiekkamäki +4
We report an experiment estimating the three parameters of a general rotation. The scheme uses quantum states attaining the ultimate precision dictated by the quantum Cramér-Rao bo…
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…
