Stochastic Schrödinger Equations: What They Mean and What They Can Do

  • H. J. Carmichael
Conference paper


The quantum mechanics we use in quantum optics is rather different from that taught in the standard quantum mechanics course. It is, of course, the same quantum mechanics; but the emphasis is different. Two observations illustrate what I mean. First, quantum optics emphasizes dissipative systems, open systems. The most notable of these is the laser, but a rather long list could be given which would include close relatives such as the parametric oscillator and a litany of systems involving resonance fluorescence. Second, quantum optics has always had close ties to the issue of quantum measurement. This theme goes back to the beginnings of the subject and Glauber’s quantum theory of coherence, which is founded on the multi-coincidence rates measured in photoelectric detection.
