Quantum physicists Eric Cavalcanti and Howard Wiseman, of Griffith University, in Queensland, Australia, and colleagues, have been awarded a portion of the prestigious 2023 Paul Ehrenfest Best Paper Award. Cavalcanti and Wiseman were recognised for their FQxI-funded paper, published in Nature Physics in 2020, "A strong no-go theorem on the Wigner's Friend Paradox." You can learn more about the Wigner's friend paradox and the implications of their research in our article "Schrödinger's AI Could Test the Foundations of Reality" by George Musser. Their team shares the prize with FQxI physicist Časlav Brukner for a paper in Entropy and FQxI physicist Renato Renner and his colleague Daniel Frauchiger for a paper in Nature Communications.
