Thank you for this! I've watched a dozen YouTube videos trying to wrap my head around the BB84 protocol, and this is by far the clearest and most concise! Excellent animation, top class narration. 😄

Best video I've seen on this topic so far!

So, you only get around 50% of the information? How does that help?
So either you have a really good error correction or you would have to send the information multiple times with a new key each time. Or am I missing something?

There are no quantum computers, who the hell is this for?

nahoj.
