Q: Can you tell me of a technological innovation which has resulted from quantum physics theory?

A: I can give you a couple: atomic bombs and silicon chips.

If you're thinking that atomic bombs were fortold by relativity physics... nope. That just says how much energy you get from an explosion. The actual process enabling an atomic explosion to happen is governed by quantum physics.

And the quantum nature of the energy state-change of silicon is what gives you the zero/one encoding that enables silicon chips to be used for making digital computing devices.
