Surprisingly, the answer is yes.<\/p>\n<p>Imagine that you have a camera cartridge that might contain a roll of photographic film. The roll is so sensitive that coming into contact with even a single photon would destroy it. With our everyday classical means there is no way there\u2019s no way to know whether there\u2019s film in the cartridge, but in the <a href=\"https:\/\/phys.org\/tags\/quantum+world\/\" rel=\"tag\" class=\"\">quantum world<\/a> it can be done. Anton Zeilinger, one of the winners of the 2022 Nobel Prize in Physics, was the first to experimentally implement the idea of an interaction-free experiment using optics.<\/p>\n<p>Now, in a study exploring the connection between the quantum and classical worlds, Shruti Dogra, John J. McCord, and Gheorghe Sorin Paraoanu of Aalto University have discovered a new and much more effective way to carry out interaction-free experiments.
