Higher-order Spatially Separated Correlations and Quantum Magic in the Long-range Transverse Field Ising Model
Paweł Cieśliński, Wiesław Laskowski
Long-range interacting quantum systems exhibit interesting phenomena beyond the nearest-neighbours regime. Such interactions can reach further separated particles and change the be…
Typicality of Steering for Two-qubit States
Gerard Anglès Munné, Paweł Cieśliński, Tamás Vértesi +1
Phenomena that slip beyond the grasp of our classical intuition reveal uniquely quantum effects that deepen our understanding of the physical world and enable advances in informati…
Unquestionable Bell theorem for interwoven frustrated down conversion processes
Paweł Cieśliński, Jan-Åke Larsson, Marcin Markiewicz +2
Interwoven frustrated parametric down conversion (PDC) processes produce interference effects based on path identity [Phys. Rev. Lett. 118, 080401 (2017)]. In this letter we show B…
How Likely Are You to Observe Non-locality with Imperfect Detection Efficiency and Random Measurement Settings?
Paweł Cieśliński, Tamás Vértesi, Mateusz Kowalczyk +1
Imperfect detection efficiency remains one of the major obstacles in achieving loophole-free Bell tests over long distances. At the same time, the challenge of establishing a commo…
