Frustration graph formalism for qudit observables
Owidiusz Makuta, BÅażej Kuzaka, Remigiusz Augusiak
The incompatibility of measurements is the key feature of quantum theory that distinguishes it from the classical description of nature. Here, we consider groups of d-outcome quant…
On Non-Existence of Stabilizer Absolutely Maximally Entangled States in Even Local Dimensions
Jakub Wójcik, Owidiusz Makuta, Wojciech Bruzda +1
We demonstrate that absolutely maximally entangled (AME) states consisting of qudits with , each of even local dimension, cannot be realized as graph stat…
Entanglement witnesses for stabilizer states and subspaces beyond qubits
Jakub Szczepaniak, Owidiusz Makuta, Remigiusz Augusiak
Genuine multipartite entanglement is arguably the most valuable form of entanglement in the multipartite case, with applications, for instance, in quantum metrology. In order to de…
Stoquastic permutationally invariant Bell operators
Jan Li, Owidiusz Makuta, Evert van Nieuwenburg +1
As Hermitian operators, many-body Bell operators can naturally be identified as many-body Hamiltonians. An important subclass of such Hamiltonians is the stoquastic class, characte…
The genuinely multipartite nonlocality of graph states is model-dependent
Xavier Coiteux-Roy, Owidiusz Makuta, Fionnuala Curran +2
Bell's theorem proves that some quantum state correlations can only be explained by bipartite non-classical resources. The notion of genuinely multipartite nonlocality (GMNL) was l…
Tailoring Bell inequalities to the qudit toric code and self testing
Eloïc Vallée, Owidiusz Makuta, Patrick Emonts +2
Bell nonlocality provides a robust scalable route to the efficient certification of quantum states. Here, we introduce a general framework for constructing Bell inequalities tailor…
