Fake violations of Bell tests reinforce importance of closing loopholes
(PhysOrg.com) -- In quantum mechanics, Bell’s inequalities serve as a test of nonclassical behavior: if something (such as a light source) violates Bell’s inequalities, then it can be considered to involve quantum ...

Physicists close two loopholes while violating local realism
(PhysOrg.com) -- The latest test in quantum mechanics provides even stronger support than before for the view that nature violates local realism and is thus in contradiction with a classical worldview. By ...

Post-Quantum Correlations: Exploring the Limits of Quantum Nonlocality
(PhysOrg.com) -- When it comes to nonlocal correlations, some correlations are more nonlocal than others. As the subject of study for several decades, nonlocal correlations (for example, quantum entanglement) ...

It's Easier to Observe the Failure of Local Realism than Previously Thought
(PhysOrg.com) -- Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly ...
