Will Quantum Computers break encryption?

How do you secure messages over the internet? How do quantum computers break it? How do you fix it? Why don't you watch the video to find out? Why does this description have so many questions? Why are you still reading? What is the meaning of life?

CLARIFICATIONS:
You don't actually need a quantum computer to do quantum-safe encryption. As briefly mentioned at 7.04 , there are encryption schemes that can be run on regular computers that can't be broken by quantum computers.

CORRECTIONS:

"The public key can only be used to scramble information." (2.18) Technically, you can use any key to encrypt or decrypt whatever you want. But there's a specific way to use them that's useful, which is what's shown in the video.

My answer on a computer science exam: ��������
Teacher: What is this supposed to mean?
Me: It's the requested 8bit answer, but expressed in qubits. It represents the correct answer if and only if you know the correct answer as well.

As a physics grad doing research in the field of quantum computing, I approve of this video.

[matiasl.ceballos]

Even though this video is about quantum computers, the explanation about how RSA encription works is THE best i've found so far for someone with no prior knowledge. It helped me a lot, and I often show this video to people who are taking their first steps in networking.
Great job!

Just watched three of your videos, and I FINALLY feel like I have an at least rudimentary understanding of quantum computers (and classical logic gates to boot). Your videos are fantastic - hope to see more in the future!

[burnhamaj]

That was a very well-made video. I really enjoyed it. You deserve way more views.

Quantam CPU: "I'm about to end this man's whole career"

Plot twist: the server is the eavesdropper

[Aveikin]

That was literally the best explanation of how encryption works I've ever seen. Finally I can fully understand it, thanks

[renatobritto]

Shit man, this video actually made me learn something hard. I find these lacking on youtube today, thanks, love this channel.

[fye]

It's fascinating how it actually take half of the video as an introduction, well explained. Thank you.

"BECAUSE QUANTUM MECHANICS!"
I laughed so hard.

[melihklc]

I have never seen a video that explains quantum better than this video. I understand you stopped making videos. I hope you come back to this work one day because you really explain it perfectly.

[dirm]

I have watched so many video that attempted to explain encryption, you were the first to actually make it clear.

[Afterscience]

First 3 CPG grey videos in a row, then Frame of Essence uploads again.
I must be in YouTube heaven.

[joebama]

can't we use quantum encryption on the quantum E-mails using Quantum Nord-Quantum-VPN? lol

[Quick_in_and_out]

So I was recently thinking to myself "will quantum computers break encryption?"

Then I find this video a day later!

Then I find out that your original title was "encryption and quantum computers" which I never would have clicked on!

Good work all round

[mikaxms]

This is such a great channel! Why did I get this channel recommended only now?

Your videos deserve more views. Maybe you should try making your videos' titles more descriptive because nobody would click on a video that is named "Encryption and Quantum Computers". Instead, name it something like "Will quantum computers break encryption?"
