Hardy’s Paradox and Violation of a State-Independent Bell Inequality in Time

Hardy’s Paradox and Violation of a State-Independent Bell Inequality in Time

Tests such as Bell's inequality and Hardy's paradox show that joint probabilities and correlations between distant particles in quantum mechanics are inconsistent with local realistic theories. Here we experimentally demonstrate these concepts in the time domain, using a photonic entangling gate to perform nondestructive measurements on a single photon at …
