Building the Bits and Qubits

What is computation? ...and what is quantum computation?

CORRECTIONS:

8:01 The Pauli-X gate does NOT flip the direction of the qubit. It rotates it 180 degrees about the x-axis, where the x-axis is pointing out of the screen.

9:41 This graph is wrong. The Shor curve should be below the Classical curve since it takes LESS time.

I came here to learn about Quantum computing, but its actually the overview of classic computing that interested me the most here. This is a fantastic visualisation of how 1's and 0's become complex computations

[skroot]

Best explanation of how classical computers process data I've seen.

It's amazing how, even though right now this channel only has 29k subscribers, this is 100% going to be one of the top tier educational channels on youtube just based off the quality of their content. If this channel doesn't have 200k+ subscribers in a year I would be shocked.

[nawarelsabaa]

As someone who studied classic computing extensively, I must say your explanation rocks! You need more subscribers.

[jakobygames]

I love knowing that in my lifetime these sciences in practice will become much more practical and likely commonplace.

[adampartridge]

This video explains quantum computing in a better detailed, not annoyingly vague, and generally better way than I've ever seen at all, while simultaneously not completely destroying my mind! The internet needs more education like this, thank you

[MIO_sh]

1:45 That bitcoin attracts my attention....

[mikikiki]

How do you not have 3 million subs, dude! This video answered so many questions I had! Thank you! Subbing and passing on this link!

[herpsenderpsen]

i love being alive in a time like this.

Wow! What a channel you have here.
I'm really glad I found you.

You'll definitely hit 100k+ subscribers soon as your illustrations and explanations are fantastic.

Thank you so much.


Big fan!

respects to the man who had to understand and memorize just for me not to be confused

[aleksandr_berdnikov]

As I understand, Pauli X-gate neither flips top-to-bottom, nor back-to-front, it rather rotates around x-axis at 2Pi (hence the name). Because if
X(|1>)=|0> and X(|0>)=|1>
then
X(|1> + i|0>) = |0> + i|1> ~ |1> - i|0>

Look at the video URL the end says qark :o

[narlycat]

i love the music at the end it was used on an Enerplex commercial and it grows on you.

[astronot]

Thank you a lot, finally I have found a video that actually says more than classic quantum sentences

[Another-Moe]

Best most to the point explanations on computation ever !

[sheepperson]

your quantum computing videos are great! thank you so much... appreciate the corrections, too. takes someone real Sincere to do that

[charlesleninja]

8:31 It can be complex...I see what you did there

[Arheisel]

In the graph at 9:45 the blue curve has negative time values, meaning that with a seemingly small number you can travel backwards in time!

I need to get one of those quantum computers to go back in time and prevent Hitl... to prevent spilling ice-cream on my pants in front of my 3rd grade crush
