Generalization of Gisin's Theorem to Quantum Fields

Konrad Schlichtholz, Marcin Markiewicz

We generalize Gisin's theorem on the relation between the entanglement of pure states and Bell non-classicality to the case of mode entanglement of separated groups of modes of qua…

Relative facts do not exist. Relational Quantum Mechanics is Incompatible with Quantum Mechanics. Response to the critique by Aurélien Drezet

Jay Lawrence, Marcin Markiewicz, Marek Żukowski

In this comment we answer to the recent critique of our article [arXiv:2208.11793] about Relational Quantum Mechanics (RQM) by Aurélien Drezet [arXiv:2209.01237]. Here we point out…

Relative Facts of Relational Quantum Mechanics are Incompatible with Quantum Mechanics

Jay Lawrence, Marcin Markiewicz, Marek Żukowski

Relational Quantum Mechanics (RQM) claims to be an interpretation of quantum theory [see arXiv:2109.09170, which appears in the Oxford Handbook of the History of Interpretation of…

Duality of averaging of quantum states over arbitrary symmetry groups revealing Schur-Weyl duality

Marcin Markiewicz, Janusz Przewocki

It is a well-established fact in quantum information theory, that uniform averaging over the collective action of a unitary group on a multipartite quantum state projects the state…

Arbitrary entanglement of three qubits via linear optics

Pawel Blasiak, Ewa Borsuk, Marcin Markiewicz

We present a linear-optical scheme for generation of an arbitrary state of three qubits. It requires only three independent particles in the input and post-selection of the coincid…

Optimal interferometry for Bellnonclassicality by a vacuumonephoton qubit

Tamoghna Das, Marcin Karczewski, Antonio Mandarino +2

Bell nonclassicality of a single photon superposition in two modes, often referred to as `nonlocality of a single photon', is one of the most striking nonclassical phenomena discus…
