Quantum optics

  1. Sep 25, 2009 #1
    Hi all.

    What topics do you find exciting in quantum optics? The reason why I am asking that I have to do an essay about a subject in quantum optics, and I would like to get a feel of the different topics in this area.

    I have recently heard of scientists who have succeeded in transferring 1 Tb (terabit) using fibre-optical cables. Is this related to quantum optics?

    Thanks for your input.

    Quantum optics is a wide field, ranging from entanglement over squeezed light towards single photon sources identified by photon antibunching. The range of topics considered to be quantum optics widened over the years. It started with resonance fluorescence, the quantum theory of optical coherence and atomic cavity QED. Meanwhile also semiconductor QED, semiconductor single photon sources and cavity optomechanics can be considered quantum optics. If you just want to hear my favorite effect in quantum optics, I would vote for the Hong-Ou-Mandel dip. This is a simple, yet astonishing and beautiful experiment.

    Not necessarily.

    Thank you for replying. I will read about the Hong-Ou-Mandel dip.

    Can it be explained by Q.M.?
