From the little I've read, and the even less I understand, it's based off of being able to use superpositioned atoms or protons or some shit to instantly transmit data, since it would theoretically exist in more than one place at the same time. It's actually very fucking interesting.

I can understand the worry and fear behind it, for sure.

But the only way humanity moves forwards technologically as a species is by doing just that, moving forward. I mean it was only a few decades ago that cell phones were the stuff of science fiction movies. And the saying goes that any substantially futuristic technology is indistinguishable from magic for the civilization that observes it and doesnt understand it.
