|The "possible" technology enabled by quantum physics? I assume you've heard of a technology of minor importance known as "semiconductors". I wish you luck with understanding semiconductors without quantum physics.|
Transistors, diodes, optoelectronic devices (solid-state lasers, solar electric cells, LEDs), and all other semiconductor devices depend on understanding of quantum physics for their design. Then, of course, there are the many other useful devices such as scanning tunneling microscopes.
I'm sure there's plenty I'm missing in the fields of nuclear physics, computational chemistry (including that used for computing protein folding today), but my own knowledge tends more towards semiconductors.
It's pretty clear from your claim that quantum physics has only "potential" technological applications that your own understanding of quantum physics' applications - potential and otherwise - is quite poor. Your conception is the popular one, but it is far from accurate. By leaving it online, you continue to mislead people on this point.
