How Does a Quantum Computer Work?

It's a brain... Js

Fun Fact: Engineers are creating the first true quantum computer.

It'll take up the size of a football field!

What types of computations/simulations would work with this quantum entanglement coding base? Is it when you consider many variables at the same time? Would artificial intelligence scripts/simulations act different?

Prediction: Once quantum computers get cheap enough, mainstream computers will contain a separate quantum processor just like they do a separate graphics processor, and programmers will find ways to exploit them in everyday applications just like we now see with multicore. It seems rather unimaginative to me to say that they're only faster at special types of calculations and leave it at that, as if those special types of calculations couldn't be found useful in all the cases they're not currently used - well, they're too slow today, aren't they? It's like saying in the 90s that broadband only would be useful for special applications, because dial-up is fast enough to load hypertext documents for home users. Failing to consider HD video streaming, because it wasn't done before it could be done.

Having now watched almost 20 videos on "how quantum computers work", I am forced to conclude that NOBODY KNOWS HOW TO MAKE A QUANTUM COMPUTER WORK!!!! Oh yeah, it sounds great to refer to Q-bits that can be 0 and 1at the same time, so N Q-bits can store 2^N bits of information --whereas N conventional transistors holds just N bits of info.
But -- SO FAR -- no-one has explained HOW you get a Q-bit to HOLD info, HOW a quantum processor would manipulate the info, and HOW THE HELL THEY GET INFORMATION/RESULTS OUT!!!

can repeat the whole thing?

So basically
2 bits - 2 storage units, each of them contains either 0 or 1
2 qubits - 2 storage units where each contains 00, 11, 1 and 0 or 0 and 1.
0's and 1's are representing the state of the storage unit. While for bits it's impossible to have state different from 0 or 1, for qubits in the 2-spin system there are 4 possible combinations, so they can store twice as much information (2qubits*2information each)
Please explain me, am I getting this correct?

i really2 want to understand, but everything he say is just wayyyyy too geeky
i need to understand

the professor guy gives me the creeps. sorry

In my understanding .
If we want to know what is 2+2 equal to, we don't need quantum com just regular one can answer us 4.
But if we want to know what 2?2=4, quantum com can find faster than regular com that it's either +,* or^, right?
Cos instead of regular com where we need to check every mathematic symbol (+,-,*,/ etc) quantum one can show the result of these 3 in one go.

Hi, can you do something. There is a video (VBDoT8o4q00&t=600s) that explains basically how a computer adds numbers with the binary system. Can you make a video that explains how quantum computer adds numbers with Qubits system. Thanks !

When you have to explain Quantum Computing in the day, but you have to play keyboard in a symphonic power metal gig in the evening

So could quantum computing be used to map out the path which the electron travels? (Travelling salesmans problem) because he said quantum computing is not faster, it just the steps until you arrive at your result is exponentially smaller 6:01

Sir , could you please tell me how does a transmitter and receiver work. Sir I hope that u would show a lot of interest in knowing how transmitter and receiver actually work..Thank You Sir.

I'm kinda disappointed how Quantum Computing won't help in normal PCs, but still, it's kinda cool

i keep believing a quantum Video card who can run every shitty port in 12K , no framerate issues.
cheap quantum GPUs when????

so if I have liquid nitrogen can I make one at home?

so the quantum computer it's no so practice for the ordinary life or the mayor part of population.

I'm a simple man... I like cake

guy is very smart
