Brazilian scientists have performed a quantum experiment that appears to be reverse the thermodynamic arrow of time. The experiment starts with two quantum correlated particles with a high degree of entropy (quantum superposition). As the experiment continues, the particles gradually unlink, thus decreasing the invidual entropy of each particle (without superposition), which woudl go against the second law of thermodynamics if the quantum correlation was not taken into account.
