Sampling the spatial coherence of light
M. Vitek, M. Peterek, D. Koutny +6
We introduce a novel application of the Hartmann sensor, traditionally designed for wavefront sensing, to measure the coherence properties of optical signals. By drawing an analogy…
Enhancing axial localization with wavefront control
M. Peterek, M. Paur, M. Vitek +6
Enhancing the ability to resolve axial details is crucial in three-dimensional optical imaging. We provide experimental evidence showcasing the ultimate precision achievable in axi…
Neural-network quantum state tomography
D. Koutny, L. Motka, Z. Hradil +2
We revisit the application of neural networks techniques to quantum state tomography. We confirm that the positivity constraint can be successfully implemented with trained network…
When quantum state tomography benefits from willful ignorance
L. Motka, M. Paur, J. Rehacek +2
We show that quantum state tomography with perfect knowledge of the measurement apparatus proves to be, in some instances, inferior to strategies discarding all information about t…
Towards quantum 3D imaging devices: the Qu3D project
Cristoforo Abbattista, Leonardo Amoruso, Samuel Burri +23
We review the advancement of the research toward the design and implementation of quantum plenoptic cameras, radically novel 3D imaging devices that exploit both momentum-position…
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…
Dispelling Rayleigh's Curse
J. Rehacek, M. Paur, B. Stoklasa +3
We devise a systematic method to determine the Fisher information required for resolving two incoherent point sources with a diffraction-limited linear imaging device. The resultin…
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…
Experimental violation of a Bell-like inequality with optical vortex beams
B. Stoklasa, L. Motka, J. Rehacek +3
Optical beams with topological singularities have a Schmidt decomposition. Hence, they display features typically associated with bipartite quantum systems; in particular, these cl…
Efficient algorithm for optimizing data pattern tomography
L. Motka, B. Stoklasa, J. Rehacek +6
We give a detailed account of an efficient search algorithm for the data pattern tomography proposed by J. Rehacek, D. Mogilevtsev, and Z. Hradil [Phys. Rev. Lett.~\textbf{105}, 01…
Time-Multiplexed Measurements of Nonclassical Light at Telecom Wavelengths
G. Harder, C. Silberhorn, J. Rehacek +4
We report the experimental reconstruction of the statistical properties of an ultrafast pulsed type-II parametric down conversion source in a periodically poled KTP waveguide at te…
Wavefront sensing reveals optical coherence
B. Stoklasa, L. Motka, J. Rehacek +2
Wavefront sensing is a set of techniques providing efficient means to ascertain the shape of an optical wavefront or its deviation from an ideal reference. Due to its wide dynamica…
