  • What's up youTube this is Christopher Ramirez coming at you with another?

  • video and look what we got going on now and as far as

  • Computers going the one of the biggest brands they have in the game

  • intel going to the next level which is quantum computing with their devices and

  • If you do not know a quantum computing is I'm gonna go ahead and have a little real play for you guys

  • To go ahead and school you on quant with quantum computers are so with that said let it roll

  • in the quantum realm physics works quite differently from the predictable ways we're used to and

  • Traditional computers, just not making sense. We are approaching a real physical barrier for our technological progress

  • to solve this problem

  • Scientists are trying to use these unusual quantum properties to their advantage by building quantum computers in

  • Normal computers bits are the smallest units of information?

  • quantum computers use qubits which can also be set to one of two values a

  • Qubit can be any two-level quantum system such as a spin in a magnetic field or a single photon

  • zero and one of this systems possible states like the photons horizontal or vertical polarization in

  • The Quantum world the qubit doesn't have to be in just one of those it can be in any proportions of both states at once

  • This is called superposition

  • But as soon as you test its value say by sending the photon through a filter it has to decide to be either

  • Vertically or horizontally?

  • polarized

  • so as long as it's unobserved the qubit is in a superposition of

  • Probabilities for 0 and 1 and you can't predict which it will be

  • That the instance you measure it it collapses into one of the definite state

  • superposition is a game changer for

  • Classical bits can be in one of two to the power of four different configurations at a time

  • There's 16 possible combinations at which you can use just one

  • For qubits in superposition however can be in all of those 16 combinations at once

  • This number grows exponentially with each extra qubit

  • Twenty of them can already store a million in parallel a really weird and unintuitive property cubits can have is

  • Entanglement a close connection that makes each of the qubits react to a change in the other state instantaneously, no matter how far

  • They are apart

  • This means that when measuring just one entangled qubits, you can directly deduce properties of its partners without having to look

  • qubit manipulation is a mind bender as well a

  • normal logic gate gets a simple set of input and produces one definite output a

  • Quantum gate manipulates an input of superpositions rotates probabilities and produces another superposition as its output

  • So a quantum computer sets up some qubits applies quantum gates to entangle them and manipulate probabilities

  • Then finally measures the outcome collapsing superpositions to an actual sequence of zeros and ones

  • What this means is that you get the entire lot of calculations that are possible with your setup all done at the same time?

  • Ultimately you can only measure one of the results

  • And it will only probably be the one you want so you may have to double check and try again

  • But by cleverly exploiting superposition and entanglement this can be exponentially more efficient than would ever be possible on a normal computer

  • So while quantum computers will probably not replace our home computers in some areas. They are vastly superior

  • One of them is database searching to find something in a database a normal computer may have to test every single one of its entries

  • Quantum algorithms read only the square root of that time which for large databases is a huge difference

  • The most famous use of Quantum computers is Rowing it security

  • Right now you're browsing

  • Email and banking Data is being kept secured by an encryption system in which you give everyone a public key to encode messages only you

  • Can decode the problem is that this public key can actually be used to calculate your secret private key

  • Luckily doing the necessary math on any normal computer would literally take years of trial and error

  • But a quantum computer with exponential speed-up could do it in a breeze

  • another really exciting new views is simulations simulations of the quantum world are very intense on resources and

  • For bigger structures such as molecules they often lack accuracy

  • So why not simulate quantum physics with actual quantum physics?

  • Quantum simulations could provide new insights on proteins that might revolutionize medicine

  • Right now we don't know if quantum computers will be just a very specialized tool or a big revolution for humanity

  • We have no idea where the limits of technology are and there's only one way to find out

  • This video is supported by the australian academy a great video. There's other videos, but I didn't want to like really drag it on

  • To too too long, but oh yeah anyhow yeah quantum computing is a really going to start taking off

  • Next to a lot of other things that's been going on in news. I don't know if y'all been paying attention to the bitcoin

  • Bitcoin if you got your digital wallet you cryptocurrency building up in your wallet. You're going to be missing out on

  • the the next spikes in the Bitcoin Community and

  • It's really interesting stuff. How that works, but I'm not going to go into detail on the bitcoin, but

  • You know I definitely do want to recommend

  • Some of the computers that they have is an intel computer I

  • Hadn't I didn't even know they had these kinds of computers for three hundred like three hundred and Eighty-two dollars really seventy-five cents?

  • I'm looking at this thing and it's got a uh it's got a sixth generation intel Core I5

  • Six two six zero so that I'm loving that shit, so you know

  • Grab that thing I mean, it's a steal I'm totally

  • for that because I just bought a six hundred dollar computer

  • but this is this is a nice deal right here because I have a desktop that don't even have an I5 and

  • That's it's kind of like moore's law to talk about you. Don't know moore's law is it means that a computing power doubles?

  • enough speed exponential growth in power and speed and and even

  • Shrinks in size

  • About about half as well, okay

  • It goes down even more in size and doubles and speed every 18 months a year and a half. That's moore's law

  • So yeah look at this you already got a piece of hardware through hundred Eighty-two dollars oh

  • Yeah, that's part of moore's law - like the price goes lower all I could look it up Moore's laws nice stuff

  • Yeah, go ahead and keep this piece of hardware out of this a nice little piece of hardware. I even know existed

  • Good to show you because I got a I got a uh this computer right here

  • since the Beach days

  • Man, I'm looking at this computers pushing like 11 years old. I'm still spotting the operating system from 11 years ago on this computer

  • It's really interesting, but you know go ahead and pick it up links in the description

  • All right get that present for you. Uh for you a friend of family Peace. I'll see you in the next video

What's up youTube this is Christopher Ramirez coming at you with another?
