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…

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…
