Released to coincide with a century of quantum mechanics and the 2025 International Year of Quantum Science and Technology, this vibrant poster teaches the basic concepts of quantum science colorfully and visually. Designed by physicists and educators to be accurate and intuitive, the poster includes sections on bits and qubits, quantum measurement, pure and mixed states, and separable and entangled states. These concepts are foundational to quantum mechanics and the rapidly expanding field of quantum information, which underlies the current development of quantum computers, quantum encryption methods, and quantum sensors. The figures accompanying each concept provide an accessible grounding for those learning about quantum topics for the first time. This item from CPEP complements its other charts on Particle Physics, Nuclear Physics, Fusion and Plasma Physics, and Gravity. CPEP is a worldwide, non-profit consortium of teacher educators and physicists. CPEP-developed materials seek to disseminate a current understanding of the fundamental physics underlying our world.
