The Paul Ehrenfest Best Paper Award is a prize for the most significant publication in the foundations of quantum physics, theoretical or experimental, during one calendar year. The aim of the award is to raise awareness for the field of quantum foundations, and to draw attention to new and interesting achievements in this area without delay. Candidate publications have to be published in a peer-reviewed journal. Other than that, papers from all areas in the foundations of quantum physics, and by authors of any background, will be eligible to receive the award.
The Paul Ehrenfest Best Paper Award for Quantum Foundations for the year 2015 was awarded jointly to three publications by groups at the TU Delft (The Netherlands), the Austrian Academy of Sciences (Austria) and the National Institute of Standards and Technology NIST (USA) for simultaneously closing the locality and detection loopholes in Bell experiments, thereby corroborating quantum mechanics and ruling out theories that satisfy local causality.
