Non-Gaussian Entanglement Hierarchy Based on the Schmidt Number
Jiajie Guo, Shuheng Liu, Matteo Fadel +1
Non-Gaussian entanglement is a promising resource in various quantum tasks. A recently defined class identifies entanglement that cannot be generated by applying Gaussian operation…
Nonlocality, Integrability and Quantum Chaos in the Spectrum of Bell Operators
Albert Aloy, Guillem Müller-Rigat, Maciej Lewenstein +2
We introduce a permutationally invariant multipartite Bell inequality for many-body three-level systems and use it to investigate a connection between Bell nonlocality and (lack of…
Theory-independent monitoring of the decoherence of a superconducting qubit with generalized contextuality
Albert Aloy, Matteo Fadel, Thomas D. Galley +2
Characterizing the nonclassicality of quantum systems under minimal assumptions is an important challenge for quantum foundations and technology. Here we introduce a theory-indepen…
Many-body -local ground states as probes for unitary quantum metrology
Majid Hassani, Mengyao Hu, Guillem Müller-Rigat +2
Multipartite quantum states saturating the Heisenberg limit of sensitivity typically require full-body correlators to be prepared. On the other hand, experimentally practical Hamil…
Three-outcome multipartite Bell inequalities: applications to dimension witnessing and spin-nematic squeezing in many-body systems
Guillem Müller-Rigat, Albert Aloy, Maciej Lewenstein +2
We present a three-outcome permutationally-invariant Bell inequality, which we show to be naturally suited to explore nonlocal correlations in many-body spin-1 systems or SU(3) mod…
Deriving three-outcome permutationally invariant Bell inequalities
Albert Aloy, Guillem Müller-Rigat, Jordi Tura +1
We present strategies to derive Bell inequalities valid for systems composed of many three-level parties. This scenario is formalized by a Bell experiment with observers, each…
