So yeah, you can theorize all you want but linking quantum physics with real-life macro applications is pretty much a pipe dream since quantum effects on a macro scale are negligible.

...wut?

Have you never walked inside of a hospital's medical imaging station? Magnetic resonance imaging is all quantum effects (inducing higher electron energy states to produce photons); positron emission tomography is the product of matter-antimatter collisions; CT scans and X-rays depend on the photoelectric effect to convert EM radiation into an intelligible electric signal. Hell, the computers have to factor in quantum tunneling from the Schrödinger Equation (which is as quantum as it gets) as a source of energy bleed. LEDs are macro applications of quantum effects, as are fluourescent bulbs for that matter.

If you haven't been paying attention, most of the innovations of post-WWII technology have made considerate use of quantum physics. I am guessing that you were just limiting your considerations to the outlandishly bizarre realm of quantum effects that occur near the Planck level. Even there you have to give credit to Hawking Radiation for saving us from the evil scientists at the LHC who would otherwise turn the Earth into a black hole. In more practical terms, conventional computing is getting to the point where More's Law will reach its limit because of the aforementioned barrier tunneling that takes place at the 10^1-2 nm scale.
