Quantum Mechianics and Telecommunications Engineering?

  1. Jul 8, 2009 #1
    Would anyone kindly tell me, in a bit detail, the applications/usefulness of Quantum Mechanics in the field of Telecommunications Engineering? I'd be thankful.

    I admit you could probably get by quite well without it, and for this reason IMO it should be an elective. But to be pedantic, everything is QM, so having at least a hand-waving understanding of it can at a minimum give you more confidence in understanding some things--like shot noise, for example. But also, don't confuse a bad teacher with a difficult subject. Introductory QM is laughably simple (when taught by a good teacher).
