The link is the term used in the quantum theory of how particles of energy / matter can be related to the alleged interaction with each other, regardless of how far they are explained.

Particles such as electrons and photons can be involved with each other in their partner as a result of enforcement of a mysterious connection. Knowing the spin state of a particle of that can be one of the spin of the particle mate / spouse know is in the opposite direction. Spin states of particles measured is decided at the time measured is then transmitted to a pair of particles, which are directly in the opposite direction of the spin of the original particle is of the opinion measured. Quantum entanglement can qubits “are separated by great distances (even light years) for direct interaction in communication interactions are not limited to the speed of light. During the isolated particles, they will still be involved no matter how great the distance.

The link is a real scientific phenomenon can be observed. Many practical research that focuses on how the potential of team involvement in the development of a system for quantum cryptography and quantum computing.
