Maxwell's tiny demon works better when light particles are indistinguishable. In an experiment with a programmable optical circuit, scientists made twin photons create a noticeable temperature difference, confirming the prediction linking heat, information, and quantum statistics. This is a step towards testing future quantum devices.
🎯 In the experiment, the temperature difference was only a few millionths of a degree, but it was detected by ultrasensitive electronics.
🎬 The idea of a demon controlling heat with information has inspired science fiction writers. For example, in 'A Fire Upon the Deep' by Vernor Vinge, superintelligent entities manipulate an invisible measure of chaos on a galactic scale.
