Continuous Fuzzy Measurement of Energy: Realization and Applicationppropriately adjusted fuzziness, information about the evolution of the state of the system ∣ψ(.)) can be read off from the measurement readout .(.). It is shown, furthermore, how a measurement of this type may be realized by a series of weak and short interactions of the 2-level system with a quantum-mechanical meter system.

MIRTH

Slow Decoherence of Superpositions of Macroscopically Distinct States mixture if exposed to the dephasing influence of a dissipative environment. Couplings to the environment with a certain symmetry can lead to . decoherence, however. We give specific examples of slowly decohering Schr?dinger cat states in a realistic quantum optical system and discuss how they might be constructed experimentally.

無能性

Decoherence in Situations Involving the Gravitational Fieldvitational degrees of freedom acquire classical properties through decoherence caused by other, irrelevant, degrees of freedom. This includes the cases of cosmo- logical variables, fluctuations in the early Universe that serve as seeds for galaxies, and black holes.

Lecture Notes in Computer ScienceIn 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.

Towards Verified Faithful SimulationThe 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.

On Martingale Central Limit TheorySeveral 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.
