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…
Unitary operator bases as universal averaging sets
Marcin Markiewicz, Konrad Schlichtholz
We provide a generalization of the idea of unitary designs to cover finite averaging over much more general operations on quantum states. Namely, we construct finite averaging sets…
On physicality of electromagnetic potential from causal structure of flux quantization
Konrad Schlichtholz, Marcin Markiewicz
Recent work by Vaidman [Phys. Rev. A 86,040101 (2012)] showed that Aharonov-Bohm effect can be explained in terms of local fields, thus effectively restating an old problem of phys…
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…
Identical particles as a genuine non-local resource
Pawel Blasiak, Marcin Markiewicz
All particles of the same type are indistinguishable, according to a fundamental quantum principle. This entails a description of many-particle states using symmetrised or anti-sym…
Relativistically invariant encoding of quantum information revisited
Konrad Schlichtholz, Marcin Markiewicz
In this work, we provide a detailed analysis of the issue of encoding of quantum information which is invariant with respect to arbitrary Lorentz transformations. We significantly…
Relational Quantum Mechanics with Cross-Perspective Links Postulate: an Internally Inconsistent Scheme
Marcin Markiewicz, Marek Żukowski
We discuss the status of relative facts - the central concept of Relational Quantum Mechanics (RQM) - in the context of the new amendment to RQM called cross-perspective links post…
"Nonlocality-of-a-single-photon" based Quantum Key Distribution and Random Number Generation schemes and their device-independent security analysis
Konrad Schlichtholz, Bianka Woloncewicz, Tamoghna Das +2
The question of ``non-locality of a single photon'', which started with a paper by Tan, Walls and Collett (TWC, 1991) stirred a thirty years long debate. This hampered attempts to…
Relational Quantum Mechanics is Still Incompatible with Quantum Mechanics
Jay Lawrence, Marcin Markiewicz, Marek Żukowski
We showed in a recent article (Lawrence et. al., 2023, Quantum 7, 1015), that relative facts (outcomes), a central concept in Relational Quantum Mechanics, are inconsistent with Qu…
