When particles fall left and right at the same time: Physicists develop new method to verify quantum entanglement

1 agosto 2014

It takes only a slight disturbance for a pencil standing on its tip to fall in one direction or another. In the quantum world it is possible in principle for particles of a system to fall both left and right at the same time. Differentiating this «and» state — the quantum entanglement of particles — from the classical «or» is an experimental challenge. Scientists have now devised a novel and universal method that enables entanglement verification for states of large atomic systems.
