geometry of quantum systems

The geometry of quantum systems involves visualizing complex states as points or directions in a high-dimensional space. These states, represented by vectors called "state vectors" or "wavefunctions," can be thought of as arrows with specific lengths and orientations. Quantum operations change these vectors smoothly, like rotating or stretching them within this abstract space, revealing relations and probabilities of different measurement outcomes. This geometric perspective helps us understand how quantum systems evolve, interfere, and become entangled, providing a powerful visual framework for grasping the underlying structure and behavior of quantum phenomena.
