As he describes how the goverment will be able to break any encryption citizens use while at the same time being able to do anything in total secrecy thanks to their quantum encryption. I know scishow just sticks with the science of things but come on how can you sound so happy with all the implications for surveillance that this has?

Given how the amount of processing power scales, you'd probably need only 310 or 320 Qubits to do that many calculations

@CybershamanX 6 жыл бұрын

+Jackson Percy That's a pretty good point, considering each qubit you add increases the computing power exponentially. But, something just occurred to me... Anybody remember the stories of when computers were freaking huge, like, building size and how the nerds of the time started coding games on those things? I wonder when we'll start hearing anecdotes about how the researchers working on quantum computers started writing games for them. I know they are planning on using them for complex simulations, at least initially. Maybe they will just use them to perform the simulation calculations for the game universe or something along those lines and then have that feed into a secondary standard machine that runs the rest of the game. I don't know, but I can almost guarantee that _someone_ is going to to do it at some point. ;) Just wait until we hear that someone ran Doom on one. heheheh :P Or, of course the perennial favorite, Crysis. (As in, "but can it run Crysis?") :P

@jaykoerner 6 жыл бұрын

Unrelated but if he was trying to be correct he would have needed to say visible universe, the whole universe might be infinite for all we know or be much more dense in matter, all we know is what we can see(ie the visible universe), the universe referes to everything and that is unmessurable

@MattJasa 6 жыл бұрын

Yea the Qubits would probably scale differently but I think Jay hit on what I was thinking. Its weird to use the universe as a measurement when we don't fully know the measure of the universe. Also how do we interface with it? Do we read and write its data digitally on a cpu?

Can you take advantage of quantum entanglement to send messages over long distances instantaneously? If so, that would make setting up a network trivial because all you have to do is send out some machines with entangled transmit/receive particles and avoid laying down a bunch of fiber optic cables.

I actually agree with your joke though, lately their videos have been a little lame. I used to tune in and actually learn something interesting but now I see dumb stuff like "Why can't your dog eat chocolate" and "why do people get nosebleeds". Like, come on sci-show. For reference this is one of the better videos. I like the videos that make you want to go out and learn more and create a vested interest in science, but when I see videos like "why don't we throw our trash in volcanoes" or "why does getting kicked in the groin hurt so much" I just want to turn my computer off. Any somewhat intelligent person would realize that testes are organs and getting hit directly in ANY organ would hurt. Sci-show used to be a place for somewhat intelligent people.

@abdulazizrushdi9154 6 жыл бұрын

Justin Cameron That's a certain type of videos called (Questions and answers) or something like that. Basically these videos aren't so much for educating as much as just answering common more life-related questions. They're typically 2-3 minutes long and in them the background is pink (or a strong shade of purple not sure). You can simply skip them. I mean, scishow creates daily videos so it's not that big of a deal if you don't like 1/2 episodes throughout the whole week.

Isn’t this how the original internet started? I remember working in large FREEZING computer rooms when I first started working, many years ago (lets just say more than 30 yrs) and everything was so top secret then too. Now look where we’ve come…all three of my kids have their own computer station set up with video systems in their “play” room that doesn’t require more than a ceiling fan because they want it on! Now, I am the one looking forward to the QUANTUM INTERNET and sure hope it’s really NOT that far off! I’ve already hit mid life, I haven’t got another 50 yrs to wait for it…I am ready to play with it NOW! Just imagine all the interesting things we could do without having to buy a FIREWALL and then still worring about getting hacked like it has happened to often lately! I am rooting for you - probably your biggest fan..in the public anyway! I love 10 01, they’re our best friends! Remember there are only two kinds of people in this world!

Just to be clear I'm not saying quantum computing won't be more secure, of course it will. Just stating a miss conception on how encryption at this point in time works. You guys are great!
