- Authors: Mois\'es Bermejo Mor\'an, Alejandro Pozas-Kerstjens and Felix Huber
- Abstract summary: We study Bell inequalities where measurements of different parties can have overlap.
This allows to accommodate problems in quantum information.
The scenarios considered show an interesting behaviour with respect to Hilbert space dimension, overlap, and symmetry.

- Abstract: Which nonlocal correlations can be obtained, when a party has access to more
than one subsystem? While traditionally nonlocality deals with spacelike
separated parties, this question becomes important with quantum technologies
that connect devices by means of small shared systems. Here we study Bell
inequalities where measurements of different parties can have overlap. This
allows to accommodate problems in quantum information such as the existence of
quantum error correction codes in the framework of non-locality. The scenarios
considered show an interesting behaviour with respect to Hilbert space
dimension, overlap, and symmetry.

We show that a temporal Clauser-Horne inequality for two spins is violated for a nonzero time interval between the measurements if the two measured parties are connected by a spin chain.
Our result suggests that, as expected in a many-body setup, the Lieb-Robinson bound substitutes the speed of light as the fundamental limit for the spreading of information.

Storing quantum information requires battling quantum decoherence, which results in a loss of information over time.
To achieve error-resistant quantum memory, one would like to store the information in a quantum superposition of degenerate states engineered in such a way that local sources of noise cannot change one state into another.
We show that this platform also allows to detect and correct certain types of errors en route to the goal of true error-resistant quantum memory.

We study general normally'' distributed random unitary transformations.
On the one hand, a normal distribution induces a unital quantum channel.
On the other hand, the diffusive random walk defines a unital quantum process.

We show that measurements on encoded qubits in two-dimensional subspaces may be performed locally.
This requires only local measurement and feed-forward of classical information.

We experimentally observe the violations of Leggett-Garg-Bell's inequalities on single and multi-qubit systems.
Our analysis highlights the limits of nowadays quantum platforms, showing that the above-mentioned correlation functions deviate from theoretical prediction as the number of qubits and the depth of the circuit grow.

We show there is a family of constant-sized correlations for which the number of measurements and number of measurement outcomes are fixed.
This places strong constraints on the types of descriptions that can be given for quantum correlation sets.
Our proof is based on a combination of techniques from quantum self-testing and from undecidability results of the third author for linear system nonlocal games.

Bell inequalities by measurements on quantum states give rise to the phenomenon of quantum non-locality.
We show that while in the so-called correlation scenario the relative violation of bilocal Bell inequalities by quantum resources is bounded, it does not grow arbitrarily with the number of inputs.
We identify Bell functionals that take the form of non-local games for which the ratio of the quantum and bilocal values grows unboundedly as a function of the number of inputs and outputs.
