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. It is awarded for the most significant paper in foundations of quantum physics, theoretical or experimental, published in a peer-review journal in the five calendar years prior to the prize call (i.e., this year we accept submissions published between Jan. 1, 2015 - Dec. 31, 2019).  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, see the rules.
