Characterization of Quantum Correlations with Local Dimension Constraints and Its Device-Independent Applications
Miguel Navascués, Gonzalo de la Torre, Tamás Vértesi · Physical Review X · 2014
Device-independent quantum cryptography protocols exploit quantum correlations generated by ``black box'' quantum devices. The physical dimensionality of such devices may act as a constraint. But which quantum correlations are fundamentally attainable and can be exploited under this constraint? Scientists now develop a new and timely numerical method that answers this question.
