Abstract
In this work we construct tests that allow a classical user to certify high dimensional entanglement
in uncharacterized and possibly noisy quantum devices. We present a family of non-local games
{Gn} that for all n certify states with entanglement of formation Ω(n). These tests can be derived from any bipartite non-local game with a classical-quantum gap. Furthermore, our tests
are noise-tolerant in the sense that fault tolerant technologies are not needed to play the games;
entanglement distributed over noisy channels can pass with high probability, making our tests
relevant for realistic experimental settings. This is in contrast to, e.g., results on self-testing of
high dimensional entanglement, which are only relevant when the noise rate goes to zero with the
system’s size n. As a corollary of our result, we supply a lower-bound on the entanglement cost
of any state achieving a quantum advantage in a bipartite non-local game. Our proof techniques
heavily rely on ideas from the work on classical and quantum parallel repetition theorems. Mehr anzeigen
