An exact semidefinite characterization of the stoquasticity cone of permutationally invariant Bell operators
Jan Li, Owidiusz Makuta, Evert van Nieuwenburg +1
Bell correlations have been detected in atomic ensembles ranging from hundreds to hundreds of thousands of particles, witnessed by the permutationally invariant (PI) Bell operators…
On Non-Existence of Absolutely Maximally Entangled Canonical Graph 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 can…
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…
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…
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…
Frustration graph formalism for qudit observables
Owidiusz Makuta, Błażej 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…
Single Bell inequality to detect genuine nonlocality in three-qubit genuinely entangled states
Ignacy Stachura, Owidiusz Makuta, Remigiusz Augusiak
It remains an open question whether every pure multipartite state that is genuinely entangled is also genuinely nonlocal. Recently, a new general construction of Bell inequalities…
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…
All genuinely entangled stabilizer subspaces are multipartite fully nonlocal
Owidiusz Makuta, Remigiusz Augusiak
Understanding which entangled states give rise to Bell nonlocality and thus are resourceful in the device-independent framework is a long-stanging unresolved problem. Here we estab…
High-dimensional monitoring and the emergence of realism via multiple observers
Alexandre C. Orthey, Pedro R. Dieguez, Owidiusz Makuta +1
Correlation is the basic mechanism of every measurement model, as one never accesses the measured system directly. Instead, correlations are created, codifying information about th…
No graph state is preparable in quantum networks with bipartite sources and no classical communication
Owidiusz Makuta, Laurens T. Ligthart, Remigiusz Augusiak
In research concerning quantum networks, it is often assumed that the parties can classically communicate with each other. However, classical communication might introduce a substa…
Fully non-positive-partial-transpose genuinely entangled subspaces
Owidiusz Makuta, Błażej Kuzaka, Remigiusz Augusiak
Genuinely entangled subspaces are a class of subspaces in the multipartite Hilbert spaces that are composed of only genuinely entangled states. They are thus an interesting object…
Self-testing of any pure entangled state with minimal number of measurements and optimal randomness certification in one-sided device-independent scenario
Shubhayan Sarkar, Jakub J. Borkała, Chellasamy Jebarathinam +3
Certification of quantum systems and their properties has become a field of intensive studies. Here, taking advantage of the one-sided device-independent scenario (known also as qu…
Self-testing maximally-dimensional genuinely entangled subspaces within the stabilizer formalism
Owidiusz Makuta, Remigiusz Augusiak
Self-testing was originally introduced as a device-independent method of certification of entangled quantum states and local measurements performed on them. Recently, in [F. Baccar…
