Information, Science, and Technology in a Quantum World

A single atom or photon can exist in a superposition of two different states, just as a sound wave can be composed of different frequencies. At LANL's Quantum Institute, the wave-particle duality of individual quanta is being exploited to develop new information technologies including quantum cryptography, quantum computing, and quantum entanglement and teleportation. Research at the Quantum Institute also encompasses studies of Bose Einstein condensates, states in which many atoms condense into a single coherent, macroscopic state, and pioneering work on the theory of quantum decoherence, the transition of a physical system from quantum to classical behavior.
