i'd wager nobody here can even explain what it is
it splits photons in 2 wavelengths

quantum computing makes the graphics on my video games betterer
faster, not better
are you moronic?
no, the only way quantum computers are better than regular ones is because they are faster.
here they list advantages / disadvantages of quantum computing, and none of them is "better graphics"

At a high level entangled particles interact with each other until the waveform is collapsed and measured. Beyond that I have no fricking idea.
Basket weaving mongoloid cartoon imageboard lurking neckbeards don't even know how regular central processing units work, let alone quantum computing.
I can't even explain classical computer at this point
Imagine you have infinite number of cores but only for some specific tasks.
Instead of 1 0 it can have 4 states for one Qubit
No idea how it works
quantum is vaporware
You mean vaporwave
Society across the globe will collapse long before this would be finished. So who cares.
fpbp
haha, silly anon, this isn't the first po…
oh
Holy shit he's fricking fugly
You can't talk about the fawtha like that you son of a b***h!
Quantum is a snake-oil meme like quadruple robots, photon-based processing is the future.
its a bullshit popsci garbage clickbait headline, so no it is not the future of pc
but quantum computing is "the future"
are you just sticking to the good ole days
If it is good enough for amazon, imagine an actual thinking tesla
>can i futureproof myself by being an early adopter of quantum pc?
It'll cost more than your house and die in 5 years.
Early adopters always get the short end of the stick.
But we need lemmings like you to pay for technological advancements we'll all enjoy.
Please cuck yourself for us.
obviously when it's ready for the consumer market
businesses will always be the true first adopters in any class for the business advantage
Consumer items aren't built the same m8
Quantum computing, as I understand it, is rather situational in its use cases.
>is quantum the future of pc?
no

are you a billionaire? then: no.
>Are you ready for microsoft infinite?
microsoft can tongue my anus
pretty much.
nobody what today is a leap towards the future
=now()+1
Fake and gay
kinda, the future is in photonics/spintronics. They will replace transistors. Quantum computers use this technology except they also need huge refrigerators so it's not practical at a commercial level. For personal computers we will see new kinds of materials used that are low power. It's all about optics/photonics/spintronics now that's the future of computer hardware.
>hey thats a nice 128 bit password you got there buddy, would be a shame if someone could crack it in 0.2 seconds
its fricking over lads, when NSA gets this its fricking over
exactly
quantum computing equates to end of privacy
only bio based encryption will save us
>child of incest can crack parent's password
Yeah, but have you ever considered that quantum encryption could become a thing?
yes, they will surely give access to a quantum computer to the public
They do and you can.
https://www.ibm.com/quantum/qiskit-runtime
There's a free plan btw.
>Yeah, but have you ever considered that quantum encryption could become a thing?
It already is.
Lattice cryptography and other quantum-resistant schemes are already developed and verified for safety and secrecy (and any other cipher metric).
>128 bit = 0.2 seconds
ok then I just make a 4096 bit password and it takes infinity time to crack again
Every bit doubles the time so 256 bits would be more than sufficient given that criteria though.
You zoomers are dumb, before posting at least just try to look up how qc work
.2 seconds is a massive exaggeration, but Grover's algorithm effectively cuts the key length in bits in half. With that a 128 bit key would be as secure as a 64 bit key, and DES was dropped for AES because the old 56 bit keys started being brute force-able in a matter of days in the late 90s. People started moving to AES-256 because of this a decade or maybe more ago.
NSA has had this tech for at least 5 years
>NSA
They can already crack your weak ass shit. They can spin up tens of thousands of servers to crack anything if they really want to. It's all about being a target worth their time.
The NSA can't crack AES 256 and even a quantum computers they won't be able to.
Unless there is some amazing new mathematical breakthrough (very unlikely) it's completely futureproof.
Quantum computers would be able to crack asymmetrical encryption, but not symmetrical.
>Quantum computers would be able to crack asymmetrical encryption, but not symmetrical.
Actually this is the whole point that some people miss.
Symmetrical cryptography with one time pad gives the HUGE benefit of perfect secrecy, at the HUGE inconvenience of key exchange.
*However* quantum communication can be tamper proof. In the sense that you have a protocol that only successfully finishes if and only there was no eavesdropping on the channel. If there's eavesdropping, the protocol fails and you start again. But as soon as the protocol completes, you can be sure that there was no information leaked to a third party, and that (qu)bits of communication were only revealed to the recipient. (Of course it's probabilistic, but you can make the error probability as small as you want, which is all you need).
This means, you can use an insecure channel to securely communicate some qubits. You use that secure communication - which kinda costly in all aspects - over the insecure channel, to exchange the (symmetric) keys. From that point onwards, you can use computationally cheap and efficient classical communication, using symmetrical ciphers and one time pad, which is gonna give you perfectly secure communication.
This is one of the huge deals of quantum in the crypto space. You can get all the huge benefits of symmetric cryptography, with all the convenience of asymmetric with regards to key exchange.
(Of course, the biggest benefit to quantum, but which you'll never see in PopSci libel, is *unspeakably* better efficiency at emulating/calculating phenomena that are quantum in nature. Anything that evolves according to a hamiltonian for instance, since quantum can do hamiltonian simulation really efficiently).
I'm not saying you're wrong or right, but if cracking an encryption takes 100 million years, spinning up ten thousand servers to do the same task would still take 10000 years...
And with a quantum computer they could cut it down to sqrt(100 million) = 10.000 years, btw.
>NOW we can plan and optimize the world economy!
They've been saying this for centuries, somehow I doubt it will happen.
This is really dangerous, every cryptography will become obsolete and all your dicky content will be revealed instantly
And my country still won't care.
kek, same. until UN makes e-girls illegal and continue raping IRL kids on third world countries. i fricking hate the UN so much, i'm thinking of commiting arson on their headquarters
>can i futureproof myself
no
The first gen consumer level quantum chip is going to be a piece of shit. You'll still be waiting a few years before it gets any good
closer to singularity
Quantum computing is the flying car of computers
It'll solve every single problem we've ever had and it'll be in your hands within 5 to 10 years for a cheap enough price that everyone will have one
I’ve been hearing that for over 10 years now.
They've had this tech for over 10 years now. The NSA intentionally starts threads like this to make it seem like it's all just one big conspiracy theory while they're secretly decrypting all your data.
protip: quantum computers aren't general purpose
the slightest variation of the encryption algorithm and they literally have to rebuild the computer specifically to solve that variant
are you worth tens of millions to them?
I mean wasn't that also the case with the colossus back in the day? I might be talking out of my ass.
here is an stackexchange discussion on quantum computers, if someone is interested

>Quantum entanglement allows permanent hardware access over internet without any wires or radio, fully faraday cage proof.
I don't feel so good schizosisters...
lol what kind of scifi moronation is that they have never even used quantum entanglement to transmit information under lab settings and most of the theories suggest you can't use it to transmit information period
Freshen up my memory, IQfyentlemen, what was the reason you couldn't use QE for FTL comms?
Something, something, you can only see that states have changed, but you cannot read the state, else the entanglement collapses or something like that?
>FTL comms
stop fricking living in scifi land
Huh? Information cannot travel faster than light, you guys do know that, right?
YOU cannot prove that.
You mean nobody can?
Maybe there are some people who can, certainly nobody who visits this site is able to prove it. At best you would get a midwit like the guy above, or some idiot linking to Wikipedia or some other paper with arcane mathematics he is unable to explain himself.
I do not believe there exists an absolute statement on the matter however, that seems insane to claim given that there obvious gaps in our understanding of physics.
actually, you can. since the speed of light is literally the highest speed there is, and theorically if you go above it you would go back in time (and become energy), the only way to send data more faster than the speed of light would be sending it to the past. at that point you are playing with some paradoxical shit at another whole level
You are just begging the question with your nonsense answer, like I said YOU cannot prove it. All you are doing is saying "X is Y".
>since the speed of light is literally the highest speed there is
Proof?
>theorically if you go above it you would go back in time (and become energy)
Proof? Absolute nonsense by the way, apparently you are such a genius you can also predict in your mind about what would happen if the thing you claim is impossible was possible. Sounds like you are high on crack.
>since the speed of light is literally the highest speed there is
>Proof?
Dude, this is literally middle school science. As an object approaches the speed of light, its mass approaches infinity.
proof?
a simple search. next time try doing it yourself, homosexual
https://www.askamathematician.com/2010/08/q-why-is-the-speed-of-light-the-fastest-speed-why-is-light-so-special/
Light isn't the fastest thing in the universe
It's the fastest known thing in the universe
why don't you try and destroy all physicists proving that light isn't the fastest way of transmitting information then? If you are so sure that light isn't the fastest, you must have a really solid proof
Light isn't the fastest thing, it's one of the things that travel at the fastest possible speed.
>Proof? Absolute nonsense by the way
is called the relativity theory, by Albert Einstein. you were home schooled or what?
here is the proof you cannot do a single search for, dipshit

>links to a 100 page website

>heres your proof bro
>QE for FTL comms
Yes anon, that's why a while back they had to throw all of physics in the garbage because it turned out that everything is wrong.
Quantum entanglement isn't for faster than light communication, that's a science miscommunication.
The particles get entangled together by Alice at her desk.
She then delivers one particle to Bob over the network. That network consists of rocket launches, lasers, post office employees, IT infrastructure.
Bob interacts with the particle in order to read it's contents. The particles are no longer entangled. Alice now has proof that Bob has received the message
In other words, quantum entanglement is like a tamper evident seal.
>that's a science miscommunication
It often is, but I'm thinking of how to use QE to communicate as an engineer.
What if Alice sends Bob eight entangled particles, and then Bob tampers the first three particles, wouldn't Alice effectively instantaneously receive 00000111 from Bob, no matter how far away he is?
>then Bob tampers the first three particles, wouldn't Alice effectively instantaneously receive 00000111 from Bob, no matter how far away he is?
The big "gotcha" is for Alice to make sense of her measurement and deduce what Bob did (i.e. get that information), she'll need to (classically) communicate something back to Bob after her measurement (or Bob to her), so in the end she can't find faster than light what Bob did.
>she'll need to (classically) communicate something back to Bob after her measurement (or Bob to her), so in the end she can't find faster than light what Bob did.
Not that guy but what if they both take 256 entangled particles split into say, 8 parts each with 32 particles and do the same process? They would have a two-way communication until they run out of particles which I assume is the main issue with that kind of communication aside from possible interference from outside factors
mentioned.
A QE battery bank?
I suppose you could, but the question then becomes how useful that actually is.
Is point-to-point actually that useful?
How about point-to-point-to-point? You could build a long-range network out of this stuff with routing tables.
But you only have so many qubits, delivered at "human speeds". You run out. Latency does not matter as much as throughput. Play some Factorio sometime.
There's an effect that I didn't mention, called decoherence.
It essentially means "your entangled qubit is no longer useful".
This is caused by interacting with it--of course, anything can interact with it, including cosmic energy, which is partly why they're cooled down so much.
So how do you expect to know when you've received the message?
Simple answer, you poll. But by polling the entangled particle you're essentially weakly interacting with it. These weak interactions will build up over time, making it impossible to maintain the entangled state for very long. This is one of the reasons why IBM insists on measuring in terms "Quantum Volume"
You have no control over the entangled photons, thus no way to send a message.
>is quantum the future of pc?
No, it does nothing really useful except crack some old encryption.
Also optical quantum computing works and is in the NSA basement. Electrical quantum computing is a giant boondoggle meant to confuse enemies.
> enemies

is qc actually real or are the existing ones not pure quantum?
Any of the stuff you saw from D-Wave was dubious quantum computing but the new stuff from Google and IBM definitely are not. The main issue is still practicality. For all intents and purposes, there still isn't enough qubits where doing a calculation on a quantum computer is worse than a classic computer. That's still a ways off from being able to use Shor's algorithm to crack current cryptography.
They are real quantum but not real computers.
Nobody has ever done a calculation with a quantum "computer".
It's like showing a single transistor and claiming it's a CPU.
Except a single transistor is actually useful, but no quantum "computer" has even done a useful thing not even in the weakest sense.
Quantum "device" would be a better word.

>is quantum the future of pc?
No, It has very limited applications.
It won't replace normal computing.
Also nobody has ever made a quantum computer yet, not even close.
what is picrel then
a pretty picture to boost stocks
Don't know but looks like CGI rendered concept art.
Definitely not a quantum computer and you must be extreme gullible if you think it is.
yep,it is the future right there with the metaverse
>futureproof
they add 2 qubits to the new model and last year's is 1000x slower

Quantum doesn't improve video game performance.
>Oh god the Juan'tom coompootas gonna crack my encryption!
Use crystal HD or swiss cheese your data till Quantum encryption comes by.
It'll never be practical for anything other than major institutions and governments. The reason it's being worked on so hard is because it will make encryption for ordinary people obsolete and allow the government to spy on literally all internet traffic in real time.
we got too wienery TORbros...
And that will spell the inevitable collapse for governments that try such a thing.
Which is what the cartel at the top running this joint really wants in order to get away with a heist and all the gold.
No one here is a psychic. Try asking /x/.
Since quantum computers haven't been made yet, we have no way of knowing if they have any practical use aside from glowBlack person shit. They might be useful for simulating chemistry and shit though.
But do know this: pop science articles regarding QC are bullshit. No, quantum computers do not perform an infinite number of computations at once. No, there is not a single blessed reason to presume that an AI running on a QC would be any more conscious than an AI running on a classical computer.
quantum computing is only appropriate for a certain kind of computational problem
general purpose quantum computers are not a thing and will probably not be for a very, very long time
How the frick is it linear?
>inb4 the electricity still has to travel in a straight line so it's linear.
It's a linear bounded automaton (as opposed to a Turing machine) because it doesn't have infinite tape
