OT: Quantum computers are BS

The only way to really know if they are full of shit is to get a PhD in quantum physics so you have the chops to call bullshit.

This is over my head - I think I saw a documentary on it and it seemed interesting.

IDK exactly what it's about or if it will work but glad they continue to push the envelope and do research that may bear fruit even if the original concept does not.

Why don't you ask the dancers at the club and see what they think

A lot of quantum physics seems like magic, but there's solid science behind it. Amazing how much established science is unintuitive.

Einstein himself had issues with quantum physics. His macro scale physics broke down at the micro subatomic level and he couldn't unify the two using mathematics.

Current computing uses binary (zeros and ones) logic to answer various computation problems. All quantum computing is doing is expanding the binary logic into tertiary and beyond. Instead of using the logic of just zeros and ones to make a TUSCL post, a quantum computer would be using multiple "states" beyond just the two. The theory of it is completely sound. The real challenge is how to make a quantum "chip" or "transistor" and then write the code from which to make a computation.

I want a working Flux Capacitor that doesn't need to use plutonium for fuel, is that really too much to ask? Ain't nobody got time for quantum computers!

^^^Mr. Fusion

@ime but just think how good porn will be with quantum computers

But, but, it's "Quantum." It's gotta work the way the say it does.

This goes right over my head ;)

Never, ever bet against technology!

Back in 1986 an engineering intern pontificated that "a 100 kilohertz computer has to be the limit because the voltage would cause current to jump across the circuits" if they were spaced as closely as would be required. I laughed and told him that he was playing a fool's game.

Thirty-three years later we have 2 to 3 GHz quad processors and 264 Gbyte memory chips that are smaller than my thumbnail and are about as thick.

I repeat, don't bet against the technology.

This doesn't seem to be the same thing but spintronics ts a developing field that measures the the quantum spin of the electrons when enough of the spins are lined up, The electron spin has two energy states, up and down, with spin 1/2. This replaces electron current.

Yes, quantum computers are legit, I have a masters in physics.

No, using a quantum computer won’t make porn better. It won’t make video games look more realistic. It really won’t do much at all to speed up your day-to-day computer activities in any direct way.

The only thing amazing that it will do is solve extremely complex problems—problems that would take a regular supercomputer days, weeks, months, to compute—in significantly shorter time (seconds). The only way this could speed up typical computers is to use the quantum computer to solve problems in the field of computer technology research (like solving some huge problem to make transistors 10% better, and then manufacturing the new transistor).

@FTS - serious question. Does the viability of QC's prove the existance of multiple dimensions?

@ATACdawg and the thing is, all that advancement was "simply" achieved through the shrinking of that binary logic transistor on a silicon substrate. The core logic never changed, staying binary the entire time. The only thing that changed was the size and switching speed of each transistor.

The issue now with speeding up a silicon based chip is that the size of the transistor "gate" at roughly 10 nanometers is approaching the size of atoms themselves at less than 1 nanometer in diameter. This is a hard limitation on how the transistor works due to quantum effects changing the material properties of it. So there is a limit approaching on the speed of a chip and already we see that with clock speeds no longer doubling every two years like they have over the last thirty. So in order to advance computing power there needs to be a solution beyond silicon chips. Quantum computing is just one possible solution.

And LOL the possibilities are endless. Think of porn that is completely computer generated with an AI that knows exactly what you want and acts like a real person with live interaction with you and also is photo real on the screen. With computer advancements our porn has become better and better. With quantum computing it will make what we watch today seem like an old blue movie on tape reel.

@FTS LOL there's still potential for porn improvements! I get what you are saying, though.

^ I was also being a bit sarcastic about the benefits of it all too.

For the record, I do think it will open up the possibility of even "smarter" interactive software.

@LoneWolf, I don’t know. To answer that question honestly requires a PhD in the subject matter. Try tweeting Sean Carroll. (Or perhaps watch one of his YouTube videos, he may have already answered that question)

Well...according to quantum physics the computers are bullshit and not bullshit so you are at least half right.

According to quantum physics there's a probability that a stripper can physically exist somewhere else in space at any given moment. It's just a really low probability but maybe not as low as her wanting to be your GF IRL.

Lol!

@SirLap: That is absolutely correct, which is exactly why you're seeing multiple processors ganged on a single chip. The challenge is then moved to software to get the full benrfit of parralel processors.
