A new record for quantum entanglement

In a significant step forward, researchers have created a quantum system entangling eight photons, eclipsing the previous record of six.

Quantum entanglement is the theory that two or more particles separated in space can have physical properties that are correlated. A measurement performed on one particle will tell us the result of the same measurement taken on an entangled particle.

While entangling relatively small groups of particles has been accomplished several times in the past 30 years, scaling these experiments up in sizes sufficient to create quantum computers and other complex systems has eluded researchers thus far.
