Experiment, ktory kazdy moze spravit doma, ilustruje jeden z najdivnejsich efektov kvantovej mechaniky

Quantum effects are not usually the kind of thing you expect to see around the house, but the May issue of Scientific American includes an experiment you can do at home that illustrates the odd phenomenon known as quantum erasure.

All it requires are a laser pointer, some polarizing film and a few household objects. You can check out the slideshow to see how it's done, discuss your efforts in the blog, or explore the supplementary material we didn't have room for in the print version of the article, including some sources of polarizing film, tips on overcoming possible problems, additional experiments you can conduct and more background on the physics involved:
