Triple slit experiment to test Feynman path integral

[Q-reeus]

A strange article today at PhysicsWorld.com: http://physicsworld.com/cws/article/new ... riple-slit
Strange firstly because it is hardly fresh news, version 1 of arXiv paper http://arxiv.org/abs/1308.2022v2 having come out over 12 months ago. Still, some here may take a keen interest in any successful experimental outcome. Also strange imo owing to the proposed setup - wavelength 4cm, 'slit' widths 120cm!
