What is an Electron? Relativistic Electron Theory and Radiative Processesst thinks that he knows what a photon is. I spent my whole life to find out what a photon is, and I still don’t know it”. And P.A.M. Dirac “I really spent my life mainly trying to find better equations for quantumelectrodynamics, and so far without success, but I continue to work on it”..

Quantum Fluctuations in Nonlinear Opticsr. These states called “squeezed states” show reduced fluctuations in one quadrature and enhanced fluctuations in the other.. They also play a general role in quantum non demolition (Q.N.D.) measurements. since the state of a system after certain Q.N.D. measurements (back action evading measurements

Selected Topics of Laser Spectroscopy of Atoms and Moleculesance for quantum-non- demolition (see lecture by D. Walls). Finally new results on Rydberg atoms will be discussed, leading to novel applications as e.g. the detection of single photons in the microwave region, being of importance for radio astronomy.

Some Remarks on the Interaction between Precision Physical Measurement and Fundamental Physical Theolly no further experimental input is needed — only an inspired expansion of the accepted postulates and mathematical arguments to structure a new reality, i.e., a new way of looking at the natural world.

Book 1983es which have been developed in quantum optics over the years. This analysis also forces one to confront certain issues in the quantum theory of measurement. The laser interferometer detectors, using as they do light, are clearly within the realm of subjects usually considered by quantum optics. For
