Alain Aspect, John Clauser and Anton Zeilinger have won the 2022 Nobel Prize in Physics for their experiments with entangled photons, in which particles of light become inextricably linked. Such experiments have laid the foundations for an abundance of quantum technologies, including quantum computers and communications. Aspect is a principal investigator for the Simons Collaboration on Localization of Waves. What We're Reading Many biologists assume that bizarre quantum phenomena play a relatively negligible role inside the cell. A recent theoretical analysis of the chemical bonds holding DNA together, however, suggests that these effects might occur far more frequently than once thought — and act as a major source of genetic mutations. A chameleon-like force that shifts its nature based on its environment could explain a major physics quandary: how the mysterious substance called dark energy is compelling the cosmos to expand faster and faster. But research published recently in Nature Physics casts doubt on some chameleon theories. Researchers at the University of Chicago and colleagues have identified a way of manipulating the spin states of the molecular qubits by placing them in an asymmetric chemical environment. The resulting spin states are more stable against noise from fluctuating magnetic fields than those in symmetric environments. For decades, scientists have been mystified about what happens to stuff that falls into a black hole. The quandary is called the black hole information paradox, and it has stopped physics in its tracks. But in recent years, scientists have made a breakthrough that may finally solve the puzzle and begin to show how black holes really work. - Previous Page - Viewing - Next Page

Nobel za fiziku došao u ruke kvantnih mehaničara Znanstvenici Alain Aspect, John Clauser i Anton Zeilinger osvojili su Nobelovu nagradu za fiziku za 2022. za postignuće ostvareno na području kvantne mehanike o ponašanju subatomskih čestica Znanstvenici Alain Aspect, John Clauser i Anton Zeilinger osvojili su Nobelovu nagradu za fiziku za 2022. za postignuće ostvareno na području kvantne mehanike o ponašanju subatomskih čestica. Time su otvorili vrata za rad na super računalima i u polju šifrirane komunikacije. Nagrada im je dodijeljena za "eksperimente koje su obavljali sa spregnutim fotonima, za utvrđivanje kršenja Bellovih nejednakosti i za pionirsko postignuće u kvantnoj informacijskoj znanosti", priopćilo je u utorak tijelo koje dodjeljuje nagrade. Kraljevska švedska akademija znanosti objavila je da su trojica laureata, francuski znanstvenik Aspect, američki znanstvenik Clauser i austrijski znanstvenik Zeilinger omogućili nastavak temeljnih istraživanja te su otvorili put za novu praktičnu tehnologiju. "Sada imamo veliko polje istraživanja koje uključuje kvantna računala, kvantne mreže i sigurnu kvantno šifriranu komunikaciju", kaže se u priopćenju. Nagradu staru više od stoljeća, vrijednu 10 milijuna švedskih kruna dodjeljuje Kraljevska švedska akademija znanosti.
