Multipartite Bell-GHZ nonclassicality from interwoven frustrated down-conversion
Marek Å»ukowski, PaweÅ CieÅliÅski, 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
PaweÅ CieÅliÅski, Jan-Ã ke 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…
"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…
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…
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…
Formal relation between Pegg-Barnett and Paul quantum phase frameworks
Tomasz Linowski, Konrad Schlichtholz, Åukasz Rudnicki
The problem of defining a hermitian quantum phase operator is nearly as old as quantum mechanics itself. Throughout the years, a number of solutions was proposed, ranging from abst…
