Abstract
Multiparticle quantum entanglement (QE) and its dynamical properties are in the focus of several experimental and theoretical fields of modern physics and engineering (e.g., quantum optics, quantum computation, quantum cryptography, and teleportation). This is due to the potential applicability of QE for quantum computers and quantum information technology. If the quantum entangled particles are sufficiently isolated from their environment, coherence can persist for long times and quantum phenomena are revealed. However, under realistic conditions, the entangled objects are continuously interacting with their environment. Thus, coherence is lost and classicality emerges. This process is called decoherence [1] and represents the main problem for the realization of a quantum computer.
