Quantum Computing

[Blade of Grass]

I've tried following this for a little bit and I still don't understand how it works, so I thought I'd share it.

Have some videos:

 

Have fun getting your mind blown 

 

EDIT: Another video (courtesy of nishank93)

I see we have similar tastes in youtube channels. :D

Do you also follow vsauce and minutephysics?

[alpenwasser]

I do indeed, yes. :)

EDIT: Numberphile and its related channels by Brady are also on my list of favourites.

Derek has got some new videos up on QuBits and transistors on 2veritasium. Check them out!

I'm going to add it to the OP.

I understood it....YAY for chemistry, never thought I would actually use it in a real world enviornment :D

some one help me out here.

 

so you have these long strings of possible out comes.

 

how do you know which one is correct if you have 3 X 10^{200 outcomes then how do you know which one is correct.}

You don't. When you measure the state of a QuBit, you will only see it as a 0 or 1 (or positive or negative spin or whatever you want to call it). The point of QuBits is that you can reduce the number of operations it takes to get to a solution but no the efficiency of each step. He explains it isn't what movies make you believe at all towards the end of the video.

Quantum mechanics is highly mathematical. Simply put, every QuBit has a certain probability of existing in one state or the other, but when measured, it will always fall into one or the other category, never somewhere in between.

We should make a physics/chemistry club.

[LuizStocco]

That was AMAZING!  :lol:

Is it so hard to understand that something can be in two different opposing places or states at the same time and still be a singular thing? i.e. one apple, two locations.

I'm just kidding (kinda). That's not at all what you guys are talking about (it's quantum mechanics).

[NeoZeon]

To understand this you must understand the wave equation. For those interested, the first semester of QM at the undergraduate level should suffice.

Making serial calculations parallel... me gusta :3

[Art Vandelay]

so what exactly can these computers do other than brute force passwords?

[mr-nipples]

My brain hurts :(
