qtum. quantum computing etf.

I like to keep up to date with scientific stuff when I can, and I recently watched a video on a breakthrough in quantum computing that says scientists are able to link three stations together quantumly, which is a major big deal that I cannot possibly comprehend. I was ok when they were entangling 2 things at a time, but linking 3 things is a new gear for me. Now I need a netflix/nova type thing to explain this to me because there is less than 3% chance I do my own research.
