It is well known that observing nonlocal correlations allows us to draw conclusions about the quantum systems under consideration. In some cases this yields a characterisation which is essentially complete, a phenomenon known as self-testing. Self-testing becomes particularly interesting if we can make the statement robust, so that it can be applied to a real experimental setup. For the simplest self-testing scenarios the most robust bounds come from the method based on operator inequalities…

Scalable Bell Inequalities for Qubit Graph States and Robust Self-Testing.
A general construction of Bell inequalities that are maximally violated by the multiqubit graph states and can be used for their robust self-testing, and numerical results indicate that the self- testing statements for graph states derived from the inequalities tolerate noise levels that are met by present experimental data.
Robust self-testing of steerable quantum assemblages and its applications on device-independent quantum certification
This work considers assemblages violating several paradigmatic Bell inequalities and obtains the robust self-testing statement for each scenario, and is device-independent (DI), i.e., no assumption is made on the shared state and the measurement devices involved.
Robust self-testing of multipartite GHZ-state measurements in quantum networks
Self-testing is a device-independent examination of quantum devices based on correlations of observed statistics. Motivated by elegant progresses on selftesting strategies for measurements [Phys.
What is the minimum CHSH score certifying that a state resembles the singlet?
This work provides a new analytical approach to explore the minimum CHSH violation leading to a non-trivial fidelity in a device-independent framework, where the fidelity bound holds without assumption about the internal working of devices used in the CHSH test.
Maximal violation of a broad class of Bell inequalities and its implication on self-testing
In quantum information, lifting is a systematic procedure that can be used to derive---when provided with a seed Bell inequality---other Bell inequalities applicable in more complicated Bell

It is found that the aforementioned Bell expression has two upper bounds in an ontological model; the usual local bound and a non-trivial preparation non-contextual bound arising from the non-Tournament parityoblivious condition, which is smaller that the local bound.
Self-testing quantum states via nonmaximal violation in Hardy's test of nonlocality
Self-testing protocols enable certification of quantum devices without demanding full knowledge about their inner workings. A typical approach in designing such protocols is based on observing
Device-Independent Certification of Genuinely Entangled Subspaces.
This work presents the first self-tests of an entangled subspace-the five-qubit code and the toric code and shows that all quantum states maximally violating a suitably chosen Bell inequality must belong to the corresponding code subspace, which remarkably includes also mixed states.
Experimental self-testing for photonic graph states.
This work experimentally demonstrated device-independent certification for multipartite graph states by adopting the robust self-testing scheme based on scalable Bell inequalities, and paves the way to the device- independent certification of complex multipartites quantum states.


Experimentally Robust Self-testing for Bipartite and Tripartite Entangled States.
A proof-of-concept demonstration of robust self-testing is achieved, which improves on the previous results significantly and describes the robustness of the used self- testing criterion.
Experimental demonstration of robust self-testing for bipartite entangled states
Chuan-Feng Li and coworkers have devised an improved method for quantum “self-testing”, meaning characterizing properties of quantum states without assuming fully-correct functioning of the measurement apparatus, but based only on the measurements’ violation of mathematical inequalities that can happen only for specific quantum states.
Self-testing of binary observables based on commutation
We consider the problem of certifying binary observables based on a Bell inequality violation alone, a task known as self-testing of measurements. We introduce a family of commutation-based measures,
Robust self-testing of the singlet
In this paper, we introduce a general framework to study the concept of robust self-testing which can be used to self-test maximally entangled pairs of qubits (EPR pairs) and local measurement
All pure bipartite entangled states can be self-tested
This work addresses the long-standing open question of whether every pure bipartite entangled state is self-testable and answers it affirmatively by providing explicit self-testing correlations for all such states.
Self-testing through EPR-steering
The verification of quantum devices is an important aspect of quantum information, especially with the emergence of more advanced experimental implementations of computation and secure communication.
Self-testing quantum states and measurements in the prepare-and-measure scenario
Self-testing methods for quantum prepare-and-measure experiments, thus not necessarily relying on entanglement and/or violation of a Bell inequality are developed, assuming an upper bound on the Hilbert space dimension.
Analytic and Nearly Optimal Self-Testing Bounds for the Clauser-Horne-Shimony-Holt and Mermin Inequalities.
This work presents a new technique for proving analytic self-testing bounds of practically relevant robustness, and derives a bound which not only improves on previously known results but turns out to be tight.
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
Self-testing in parallel
Self-testing allows us to determine, through classical interaction only, whether some players in a non-local game share particular quantum states. Most work on self-testing has concentrated on
