The tactile interface for the Public Quantum Network is a polarimeter setup that lets users observe and interact with the polarization of light — a direct demonstration of quantum superposition.
Lab-grade polarimeter systems cost several hundred to several thousand dollars, creating a significant barrier to public engagement. To address this, the PQN provides an inexpensive, modular alternative built from 3D-printed components and affordable optics that replicates the same visual effects at a fraction of the cost.
The design files (STL and CAD) are available in the PQN hardware repository so nodes can print the parts directly or adapt the dimensions to their needs.
