Quantum physics analyzes a quantum system (QS) that has the ability to exist in a superposition of different states, simultaneously. Lately, scientists have developed computers, which are based on quantum mechanical principles, instead of classical physics.
Researchers and physicists from the Max Planck Institute generated a photon pair from the energy of an electron through a light source. The first photon will be used for quantum information transmission, while the other will be observed, as it displays the specific state of its twin, at any time. This is what we call entanglement.
