    "abstract": "The three-box problem is a gedankenexperiment designed to elucidate some\ninteresting features of quantum measurement and locality. A particle is\nprepared in a particular superposition of three boxes, and later found in a\ndifferent (but nonorthogonal) superposition. It was predicted that appropriate\n\"weak\" measurements of particle position in the interval between preparation\nand post-selection would find the particle in two different places, each with\ncertainty. We verify these predictions in an optical experiment and address the\nissues of locality and of negative probability.",
