The violation of a Bell inequality is the paradigmatic example of device-independent quantum information: the nonclassicality of the data is certified without the knowledge of the functioning of devices. In practice, however, all Bell experiments rely on the precise understanding of the underlying physical mechanisms. Given that, it is natural to ask: Can one witness nonclassical behaviour in a truly black-box scenario? Here we propose and implement, computationally and experimentally, a… 

Dynamical learning of a photonics quantum-state engineering process

Abstract. Experimental engineering of high-dimensional quantum states is a crucial task for several quantum information protocols. However, a high degree of precision in the characterization of the

Photonic Implementation of Quantum Gravity Simulator

Detecting gravity mediated entanglement can provide evidence that the gravitational field obeys quantum mechanics. We report the result of a simulation of the phenomenon using a photonic platform. The

Experimental violation of local causality in a quantum network

TLDR
This work investigates a quantum network consisting of three spatially separated nodes whose correlations are mediated by two distinct sources, and experimentally witness the emergence of the so-called non-bilocal correlations by violating a Bell-like inequality under the fair-sampling assumption.

Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres

TLDR
The data imply statistically significant rejection of the local-realist null hypothesis and could be used for testing less-conventional theories, and for implementing device-independent quantum-secure communication and randomness certification.

Significant-Loophole-Free Test of Bell's Theorem with Entangled Photons.

TLDR
A Bell test is reported that closes the most significant of loopholes that provide loopholes for a local realist explanation of quantum mechanics, using a well-optimized source of entangled photons, rapid setting generation, and highly efficient superconducting detectors.

Device-independent randomness generation from several Bell estimators

TLDR
Protocols for device-independent randomness generation, secure against classical side information, that rely on the estimation of an arbitrary number of Bell expressions or even directly on the experimental frequencies of measurement outcomes are introduced.

Self-testing protocols based on the chained Bell inequalities

Self-testing is a device-independent technique based on non-local correlations whose aim is to certify the effective uniqueness of the quantum state and measurements needed to produce these

Experimental device-independent certified randomness generation with an instrumental causal structure

TLDR
The authors present a proof-of principle implementation of a device-independent random number generator protocol, whose effectiveness is certified by quantum instrumental correlations, which also ensures privacy with respect to any quantum adversarial attack.

Experimental violation of n-locality in a star quantum network

TLDR
A chained n-locality inequality is violated in a network with five nodes and four independent sources, relying only on single-qubit measurements to witness the emergence of nonlocal correlations among the nodes of the implemented networks.

Experimental Robust Self-Testing of the State Generated by a Quantum Network

TLDR
This work experimentally implements two significant building blocks of a quantum network involving two independent sources, i.e. a parallel configuration in which two parties share two copies of a state, and a tripartite configuration where a central node shares two independent states with peripheral nodes.

Imperfect measurement settings: Implications for quantum state tomography and entanglement witnesses

Reliable and well-characterized quantum resources are indispensable ingredients in quantum information processing. Typically, in a realistic characterization of these resources, apparatuses come with

Machine Learning Nonlocal Correlations.

TLDR
Not only can the machine learn to quantify nonlocality, but discover new kinds of nonlocal correlations inaccessible with other current methods as well, and the framework is applied to distinguish between classical, quantum, and even postquantum correlations.
