Measurement of the influence of dispersion on white-light interferometry
Pavel Pavliček,Jan Soubusta +1 more
TL;DR: This work investigates the influence of setup parameters on the shape of the correlogram of white-light interferometry, a well-established method for measuring the height profiles of samples with rough as well as with smooth surfaces.

Entanglement-based linear-optical qubit amplifier
Evan Meyer-Scott,Marek Bula,Karol Bartkiewicz,Antonín Černoch,Jan Soubusta,Thomas Jennewein,Karel Lemr +6 more
TL;DR: In this article, a linear-optical scheme for an efficient amplification of a photonic qubit based on interaction of the signal mode with a pair of entangled ancillae was proposed.

Experimental implementation of the optimal linear-optical controlled phase gate.
TL;DR: This work experimentally explored the remarkable observation that the optimum success probability is not monotone in the phase, and realized scheme is entirely flexible in that the phase shift can be tuned to any given value.
Theoretical measurement uncertainty of white-light interferometry on rough surfaces
Pavel Pavliček,Jan Soubusta +1 more
TL;DR: The theoretical limits of the longitudinal uncertainty is derived by virtue of the first-order statistics of the speckle pattern of the white-light interferometry for profile objects with a rough surface.

Several experimental realizations of symmetric phase-covariant quantum cloners of single-photon qubits
TL;DR: In this article, the authors compare several optical implementations of phase-covariant cloning machines, based on copying of the polarization state of a single photon in bulk optics by a special unbalanced beam splitter or by a balanced beam-splitter accompanied by a state filtering.
