Quantum Newton's Cradle with Bose-Einstein Condensates

Newton's cradle is a valuable paradigm of how physical mechanisms are concealed into nature. It is a device based on classical mechanics that demonstrates the conservation of momentum and energy. On the other hand, Quantum Mechanics has been shown to be one of most prolific sources of unexpected and hard-to-understand phenomena. Therefore, achieving a machine which is a paradigm for the quantum nature of a system is an engrossing challenge. We propose a possible experimental realization of a quantum analogue of Newton's cradle (NC).
