Self-testing using only marginal information
arXiv:1808.02223 · doi:10.1103/PhysRevA.98.052331
Abstract
The partial states of a multipartite quantum state may carry a lot of information: in some cases, they determine the global state uniquely. This result is known for tomographic information, that is for fully characterized measurements. We extend it to the device-independent framework by exhibiting sets of two-party correlations that self-test pure three-qubit states.
