Quantification of the energy consumption of entanglement distribution

Karol Horodecki, Marek Winczewski, Leonard Sikorski +3

Inspired by environmental sciences, we develop a framework to quantify the energy needed to generate quantum entanglement via noisy quantum channels, focusing on the hardware-indep…

Benchmarking weak randomness in Quantum and Natural Sources

Maciej Stankiewicz, Roberto Salazar, Mikołaj Czechlewski +7

Private randomness is a fundamental resource for cryptography, security proofs, and information processing. Quantum devices offer a unique advantage by amplifying weak randomness s…

Device independent witness of arbitrary dimensional quantum systems employing binary outcome measurements

Mikołaj Czechlewski, Debashis Saha, Armin Tavakoli +1

Device independent dimension witnesses (DW) are a remarkable way to test the dimension of a quantum system in a prepare-and-measure scenario imposing minimal assumptions on the int…

The influence of the choice of post-processing method on Bell inequalities

Mikołaj Czechlewski, Marcin Pawłowski

In every experimental test of a Bell inequality, we are faced with the problem of inefficient detectors. How we treat the events when no particle was detected has a big influence o…

Distillation of entanglement by projection on permutationally invariant subspaces

Mikołaj Czechlewski, Andrzej Grudka, Michał Horodecki +2

We consider distillation of entanglement from two qubit states which are mixtures of three mutually orthogonal states: two pure entangled states and one pure product state. We dist…

Violation of Clauser-Horne-Shimony-Holt inequality for states resulting from entanglement swapping

Antoni Wojcik, Joanna Modlawska, Andrzej Grudka +1

We consider violation of CHSH inequality for states before and after entanglement swapping. We present a pair of initial states which do not violate CHSH inequality however the fin…
