Multiparameter Quantum Metrology of Incoherent Point Sources: Towards Realistic Superresolution
J. Rehacek, Z. Hradil, B. Stoklasa +4
We establish the multiparameter quantum Cramér-Rao bound for simultaneously estimating the centroid, the separation, and the relative intensities of two incoherent optical point so…
Unraveling beam self-healing
Andrea Aiello, Girish S. Agarwal, Martin Paúr +6
We show that, contrary to popular belief, non only diffraction-free beams may reconstruct themselves after hitting an opaque obstacle but also, for example, Gaussian beams. We unra…
Efficient tomography with unknown detectors
L. Motka, M. Paur, J. Rehacek +2
We compare the two main techniques used for estimating the state of a physical system from unknown measurements: standard detector tomography and data-pattern tomography. Adopting…
Achieving quantum-limited optical resolution
Martin Paur, Bohumil Stoklasa, Zdenek Hradil +2
We establish a simple method to assess the quantum Fisher information required for resolving two incoherent point sources with an imaging system. The resulting Cramér-Rao bound sho…
