“Quantum cryptography will begin to be used in diplomacy, the military and finance”, says Nobel Prize in Physics to Expresso

French physicist Alain Aspect made history with two photons that ended up supplanting a famous disagreement between Niels Bohr and Albert Einstein in the first half of the 20th century. With a laboratory experiment, which used mirrors and polarization, the researcher was able to send two particles of light in opposite directions and ensure that they maintained the same state in common, despite the distance. And that is why it is said that these particles were intertwined.
