Quantum Measurements and Decoherence: Models and Phenomenology

Quantum measurement (Le., a measurement which is sufficiently precise for quantum effects to be essential) was always one of the most important points in quantum mechanics because it most evidently revealed the difference between quantum and classical physics. Now quantum measure­ ment is again under active investigation, first of all because of the practical necessity of dealing with highly precise and complicated measurements. The nature of quantum measurement has become understood much b...
