Multipartite Bell-GHZ nonclassicality from interwoven frustrated down-conversion
Marek Żukowski, Paweł Cieśliński, Marcin Markiewicz +1
We present a theory of an interference process that starts with N coherently pumped two-mode parametric down-conversion (PDC) sources, whose output modes are directed to N observer…

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…

Against (unitary) interpretation (of quantum mechanics): removing the metaphysical load
Marek Żukowski, Marcin Markiewicz
In June 1925 Heisenberg arrived at Helgoland/Heligoland island to escape a fit of hay fever. He returned with a sketch of a strange theory of the micro-world, which we now call qua…
