quantum entanglement

[‚kwän·təm in′taŋ·gəl·mənt]
(quantum mechanics)
The property of two particles with a common origin whereby a measurement on one of the particles determines not only its quantum state but the quantum state of the other particle as well.

They were able to attain this entangled state 88 percent of the time.
Of course, because of the above reasons, two particles can not be in entangled state if they are located in the basic space-time of General Relativity--the four-dimensional pseudo-Riemannian space with sign-alternating label (+ ) or (-+++).
The result is one set of four photons forming an entangled state that circulates around the interferometer in one direction, accompanied by another entangled quadruplet circulating in the other direction.
In 1935, Einstein, Podolsky and Rosen (EPR) challenged a particular prediction of quantum theory saying that two particles can exist in a so-called entangled state in which the two particles do not have individually defined ( local ) positions and momenta.
Once two objects are put in an entangled state, their properties are inextricably entwined.
