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…

Evidence-based certification of quantum dimensions

Y. S. Teo, H. Jeong, N. Prasannan +5

Identifying a reasonably small Hilbert space that completely describes an unknown quantum state is crucial for efficient quantum information processing. We introduce a general dime…

Covariant operator bases for continuous variables

A. Z. Goldberg, A. B. Klimov, G. Leuchs +1

Coherent-state representations are a standard tool to deal with continuous-variable systems, as they allow one to efficiently visualize quantum states in phase space. Here, we work…

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…

Local sampling of the Wigner function at telecom wavelength with loss-tolerant detection of photon statistics

G. Harder, Ch. Silberhorn, J. Rehacek +4

We report the experimental point-by-point sampling of the Wigner function for nonclassical states created in an ultrafast pulsed type-II parametric down-conversion source. We use a…
