The first quantum revolution, based on wave-particle duality, started in the early 1900's. It dramatically modified our vision of the microscopic world. It permitted the invention of technologies that have dramatically changed the society. The second quantum revolution is based on a yet stranger concept, entanglement. We do not know yet if it will impact the society as much as the first quantum revolution.
