Generalized self-testing and the security of the 6-state protocol

McKague, Matthew, Mosca, Michele

Understand

Self-tested quantum information processing provides a means for doing useful information processing with untrusted quantum apparatus.

  • Previous work was limited to performing computations and protocols in real Hilbert spaces, which is not a serious obstacle if one is only interested in final measurement statistics being correct (for example, getting the correct factors of a large number after running Shor's factoring algorithm).
  • This limitation was shown by McKague et al.
  • to be fundamental, since there is no way to experimentally distinguish any quantum experiment from a special simulation using states and operators with only real coefficients.
