    What are some real life examples or consequences of quantum theory?
    I.E-new technologies... and such.

    The transistor, which almost all modern electronics are based upon, is one of the most important examples.

    The laser and the SQUID, for two more. All of modern chemistry (students who take high school chemistry get more quantum mechanics than those who take high school physics).

    (that's solid-state electronics; the valves etc are pure classical physics)

    Other examples: diode laser (e.g. in your CD player), superconductors (so MRI equipment, for example), CCDs (e.g. your digital camera), SQUIDs, ...

    I suppose the Scanning Tunnelling Microscope is an excellent application how one uses the quantum tunnelling effect.

    How about Photonic Crystals. They can be used to make surface-emitting quantum-cascade lasers.
