Physics of the University of Glasgow in Scotland was the first in the history of the quantum entanglement phenomena that Einstein called “scary action at a distance”. This publication reports Science Alert.
The researchers designed the plant, generating streams of entangled photons. In this state the particles in a pair have the interrelated quantum States. For example, when measuring the spin of one particle, you can predict what the spin will have a second particle. The change in the quantum state of one particle instantaneously alters the state of another, no matter how far that was.
To install a pair of entangled photons split, with one beam passed through the four liquid crystal filter, undergoing phase transitions. The photons in the second beam also experienced a phase transition, although not passed through the crystals. The camera recorded the distribution of particles in both beams.
According to scientists, the results of the experiment demonstrated the violation of bell’s inequality on visible images. The bell inequalities suggest the presence of hidden variables that would explain quantum entanglement and which can be detected in a series of experiments. However, until now, such parameters have not been observed, which confirms the existence of long-range interaction.
