Sensitivity versus selectivity in entanglement detection via collective witnesses
Vojtěch Trávníček, Jan Roik, Karol Bartkiewicz +3
In this paper, we present a supervised learning technique that utilizes artificial neural networks to design new collective entanglement witnesses for two-qubit and qubit-qutrit sy…
Experimental measurement of Hilbert-Schmidt distance between two-qubit states as means for speeding-up machine learning
Vojtěch Trávníček, Karol Bartkiewicz, Antonín Černoch +1
We report on experimental measurement of the Hilbert-Schmidt distance between two two-qubit states by many-particle interference. We demonstrate that our three-step method for meas…
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…
