Quantum randomness protected against detection loophole attacks
Piotr Mironowicz, Gustavo Cañas, Jaime Cariñe +6
Device and semi-device independent quantum randomness generators (DI- and SDI-QRNGs) are crucial for applications requiring private randomness. However, they are vulnerable to dete…
Detection efficiency loophole in Pusey-Barrett-Rudolph theorem
Arijit Dutta, Marcin Pawlowski, Marek Zukowski
Detection efficiency loophole poses a significant problem for experimental tests of Bell inequalities. Recently discovered Pusey-Barrett-Rudolph (PBR) theorem suffers from the same…
Properties of dimension witnesses and their semi-definite programming relaxations
Piotr Mironowicz, Hong-Wei Li, Marcin Pawłowski
In this paper we develop a method for investigating semi-device-independent randomness expansion protocols that was introduced in [Li et al., Phys. Rev. A , 020302(R)…
Device-independent randomness extraction for arbitrarily weak min-entropy source
Jan Bouda, Marcin Pawlowski, Matej Pivoluska +1
Expansion and amplification of weak randomness plays a crucial role in many security protocols. Using quantum devices, such procedure is possible even without trusting the devices…
Device and semi-device independent random numbers based on non-inequality paradox
Hong-Wei Li, Marcin Pawlowski, Ramij Rahaman +2
In this work, we propose device independent true random numbers generation protocols based on non-inequality paradoxes such as Hardy's and Cabello's non-locality argument. The effi…
Intrinsic asymmetry with respect to adversary: new feature of Bell inequalities
P. Horodecki, M. Pawlowski, R. Horodecki
It is known that the local bound of a Bell inequality is sensitive to the knowledge of the external observer about the settings statistics. Here we ask how that sensitivity depends…
