Query: Experimental comparison of tomography and self-testing in certifying
  entanglement   We assess the quality of a source of allegedly pure two-qubit states using
both standard tomography and methods inspired by device-independent
self-testing. Even when the detection and locality loopholes are open, the
latter methods can dispense with modelling of the system and the measurements.
However, due to finite sample fluctuations, the estimated probability
distribution usually does not satisfy the no-signaling conditions exactly. We
implement data analysis that is robust against these fluctuations. We
demonstrate a high ratio $f_s/f_t\approx 0.988$ between the fidelity estimated
from self-testing and that estimated from full tomography, proving high
performance of self-testing methods.
