Artists are increasingly exploring the intersection of art and quantum physics, designing outdoor sculptures that metaphorically or literally interact with the quantum multiverse. By incorporating principles like superposition, entanglement, and multidimensionality, these works challenge viewers to perceive reality beyond classical boundaries. Some use reflective surfaces to create infinite visual recursion, symbolizing parallel universes, while others employ responsive technology that changes with environmental variables—echoing quantum unpredictability. Light-based installations might mimic wave-particle duality, and kinetic sculptures could represent collapsing probabilities. The fusion of scientific theory with public art not only democratizes complex ideas but also redefines how we experience space, time, and existence. These creations invite audiences to question: Is the artwork observing us as we observe it?
