Experimental diagnostics of entanglement swapping by a collective entanglement test

Vojtěch Trávníček, Karol Bartkiewicz, Antonín Černoch +1

The paper reports on experimental diagnostics of entanglement swapping protocol by means of collective entanglement witness. Our approach is suitable to detect disturbances occurri…

Interplay between strong and weak measurement: Comparison of three experimental approaches to weak value estimation

Jan Roik, Karel Lemr, Antonín Černoch +1

Weak values are traditionally obtained using a weak interaction between the measured system and a pointer state. It has, however, been pointed out that weak coupling can be replace…

Experimental tests of coherence and entanglement conservation

Antonín Černoch, Karol Bartkiewicz, Karel Lemr +1

We experimentally demonstrate the migration of coherence between composite quantum systems and their subsystems. The quantum systems are implemented using polarization states of ph…

Experimental characterization of photon-number noise in Rarity-Tapster type interferometers

Vojtěch Trávníček, Karol Bartkiewicz, Antonín Černoch +1

In this paper, we develop a simple model describing inherent photon-number noise in Rarity-Tapster type interferometers. This noise is caused by generating photon pairs in the proc…

Bell nonlocality and fully-entangled fraction measured in an entanglement-swapping device without quantum state tomography

Karol Bartkiewicz, Karel Lemr, Antonín Černoch +1

We demonstrate an efficient experimental procedure based on entanglement swapping to determine the Bell nonlocality measure of Horodecki et al. [Phys. Lett. A 200, 340 (1995)] and…

Measuring evolution of a photon in an interferometer with spectrally-resolved modes

Marek Bula, Karol Bartkiewicz, Antonín Černoch +4

In the year 2013, Danan et al. published a paper [Phys. Rev. Lett. 111, 240402 (2013)] demonstrating a counterintuitive behavior of photons in nested Mach-Zehnder interferometers.…
