The Peres conjecture is false: One of the most famous problems in quantum information physics solved
Since 1999, the conjecture by Asher Peres, who invented quantum teleportation, has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result ...
