Elements of Environmental DecoherenceIn this contribution I give an introduction to the essential concepts and mechanisms of decoherence by the environment. The emphasis will be not so much on technical details but rather on conceptual issues and the impact on the interpretation problem of quantum theory.

Mathematical Aspects of DecoherenceThe aim of this lecture is to investigate the mathematical frame for environment induced superselection rules. Some exactly soluble models are dicussed in detail and norm estimates on decoherence effects are derived.

Dynamical Localization and DecoherenceWe study the influence of spontaneous emission on dynamical localization in the motion of atoms.

Quantum Cryptography and Long Distance Bell Experiments: How to Control DecoherenceSeveral mechanisms that affect one and two photon coherence in optical fibers and their remedies are discussed. The results axe illustrated on quantum cryptography experiments and on long distance Bell inequality tests.

We give specific examples of slowly decohering Schrödinger cat states in a realistic quantum optical system and discuss how they might

Towards Verified Faithful Simulationkets are accelerated towards each other, start to overlap, and an interference pattern emerges. When the particle is coupled to the radiation field, assumed to be in a thermal state, the interference pattern is partially suppressed, which defines the decoherence amplitude. For our model we compute b

https://doi.org/10.1007/978-3-319-25942-0l question is whether such dynamical processes are eventually also responsible for at least some of the superselection rules which are usually presented as fundamentally rooted in the kinematical structure of the theory (so called ‘hard’ superselection rules). With this question in mind, I re-invest
