The Nobel Prize in Physics rewards the 'fathers' of quantum information

The 'rules of the game'< /strong> that govern our reality do not always apply in the atomic world. A very illustrative example, as well as a poetic one, is what happens when two particles, even if they are very far apart, they behave as a single unit. the why How this phenomenon, known as quantum entanglement, has fueled debate among scientists for decades. For this very reason, this year's Nobel Prize in Physics has decided to honor the work of three researchers who have managed to 'decipher' part of the mystery and who, in turn, have emerged as the 'fathers' of quantum information: Alain Aspect, John F. Clauser and Anton Zilinger.

As argued by the committee Nobel Prize winner, the experimental work of these scientists has “laid the foundations for a new era of quantum technology“. “Being able to manipulate and manage quantum states and all their layers of properties gives us access tools with unexpected potential“, says the panel of experts responsible for this award. ;n. In this sense, the findings could be used, one day, to It was possible to build quantum computers, build quantum networks and establish more secure encrypted communication, precisely thanks to quantum technology.

“I am very excited to see that the Nobel Prize in Physics has finally been awarded to the fundamentals of quantum physics“, explains Alba Cervera Lierta >, expert researcher in quantum computing at the Barcelona Supercomputing Center and coordinator of Quantum Spain. “These findings led to the beginning of using quantum properties to develop new forms of communication and computing. sica: this is a Nobel that recognizes the power of quantum mechanics“, comments the expert in statements to the Science Media Center Spain.

The Nobel Prize winners who disproved Einstein

The experiments of Aspect (France, 1947), Clauser (United States, 1942) and < strong>Zilinger (Austria, 1945) have marked a milestone in quantum physics. His experiments to demonstrate how particle entanglement occurs have also, paradoxically, 'disproved' the postulatesof one of the most famous physicists of all time: Albert Einstein. At the dawn of quantum theories, in fact, Einstein showed himself I was horrified at the idea of some particles intertwining at a distance. defined he dismissed the idea as a “creepy action” the famous phrase of “God does not play dice” to show his rejection of the idea of ​​quantum mechanics.

< p>This year's Physics Nobels, in a way, prove that Einstein was wrong. And that, effectively, the quantum world is governed by its own rules. One of the most striking works carried out by this year's winners is that of Anton Zeilinger, who has not only managed to 'tame' entangled quantum states but has also , has managed to demonstrate a phenomenon known as quantum teleportation: the possibility of moving a quantum state from one particle to another, no matter how far apart they are.

Nobel Season

The Physics award is the second to be awarded in this year's Nobel season, which started in June. no clear favouritesand with widespread criticism for the lack of women among the awardees. Throughout the history of these awards, among the 221 winners in the area of ​​Physicsthere are only four women scientists. In the previous edition, this category distinguished the works ofSyukuro Manabe, Klaus Hasselmann and Giorgio Parisi on “the science to understand the progress of the climate crisis” and other complex systems.

Tomorrow, Wednesday the 5th, the report will be delivered. the Nobel Prize in Chemistry, the last purely scientific award of this Nobel season. Last year, the recognition went to the researchers David MacMillan and Benjamin List for “the art of creating organic molecules.” to be known as of 11:45 (Spanish peninsular time). On the eve of delivery, the pools among the experts are still uncertain.
