Quantum-Mechanical Entanglement Takes Center Stage at Attosecond Laser Laboratory

Quantum mechanics is famous for the way that its predictions challenge intuitive human thinking developed through the way that we experience the everyday world around us. Among other things, quantum objects can display both particle- and wave-like character, can interfere and can occur in the form of quantum superpositions.

Hyperchaos in the Mid-Infrared Regime Produced from Interband Cascade Lasers

Chaos, popular as butterfly effect, describes the irregular phenomenon of deterministic systems. Based on the unique features of sensitivity to initial conditions and unpredictability to future evolutions, chaos from laser diodes have found applications in private optical communication links, high-rate random number generations, Lidar systems, as well as recent optical computing networks.
