Welcome to the Quantum dimension! Join Alice and Bob in their journey into the quantum world in the three "subway" lines U1, U2 ans U3. Each station of the subway lines deals with topics in quantum physics, which together allow for an understanding of the standard model of particle physics with symmetry group U1xU2xU3. The idea for the project QuantumVisions dates back to the year 1998, when Stefan Heusler started his production of short non-budget animation movies dealing with topics in quantum physics. In the last decades, a visual language has emerged, aiming at haptic and visual models for quantum states. In particular, qubits as simplest possible quantum states play a special role for all visualizations. More publictations and informations can be found at http://www.quantumvisions.net/en/
