Experimental hierarchy and optimal robustness of quantum correlations of two-qubit states with controllable white noise
Experimental hierarchy and optimal robustness of quantum correlations of two-qubit states with controllable white noise
We demonstrate a hierarchy of various classes of quantum correlations on experimentally prepared two-qubit Werner-like states with controllable white noise. Werner states, which are white-noise-affected Bell states, are prototypal examples for studying such a hierarchy as a function of the amount of white noise. We experimentally generated Werner states and …
