Photon Bricks: A Lego set for playful quantum explorations

Researchers from the University of Nottingham’s Gravity Laboratory, alongside student LEGO enthusiasts, have developed unique LEGO-based interferometer kits to make quantum science more accessible and engaging. The kits are designed for secondary and older pupils, embracing a hands-on approach with LEGO bricks that are suitable for classroom use. The fully functional LEGO interferometer sets are designed to replicate professional optical equipment, bridging the gap between abstract concepts of cutting-edge technology and tangible demonstrations that captivate live audiences. With easy-to-follow instructions, these kits serve as valuable teaching aids, inspiring the next generation of scientists. Featuring lasers, mirrors, and beamsplitters, the kits demonstrate the principles of interferometry. When two laser beams are combined, they create a delicate, alternating pattern of dark and bright stripes, known as an interference pattern. This pattern is highly sensitive to even the tini ...
