# A weak form of self-testing

@article{Kaniewski2019AWF, title={A weak form of self-testing}, author={J. Kaniewski}, journal={arXiv: Quantum Physics}, year={2019} }

The concept of self-testing (or rigidity) refers to the fact that for certain Bell inequalities the maximal violation can be achieved in an essentially unique manner. In this work we present a family of Bell inequalities which are maximally violated by multiple inequivalent quantum realisations. We completely characterise the quantum realisations achieving the maximal violation and we show that each of them requires a maximally entangled state of two qubits. This implies the existence of a new… Expand
