Abstract:

We derive a framework for quantifying entanglement in multipartite and high dimensional systems using only correlations in two mutually unbiased bases. We furthermore develop such bounds in cases where the second basis is not characterized, thus enabling entanglement quantification with minimal assumptions. To demonstrate the experimental feasibility of the approach we develop an experimental proposal with state of the art cameras and optical lenses and show that these methods enable a reliable characterization of sources of entangled photons with minimal effort.
