Quantum Computers are already at hand, and now they're developing more effective ways to send over particles.
How close do y'all think we are to having wide access quantum entangled internet?
I think it's approproate that no one can dicide if d-wave's microchip is actually a quantum computer. It appears to exist in a state of flux depending on the observer. To some scientists, its a quantum computer, to other scientists, it's not.
right. more rhetorical, but still, right.
I may be missing a large portion of the process, I'm reading up on it now. If you can humor me a little more. Once it's sent and setup, can't you just send a spin one way, causing both to spin, and then stop it on the other side instantly, stopping both, and have the receiver tally a mark saying that the information was sent. Kind of like morse code?
Entaglement just means that when you create 2 particles out of an particle with value 0, you get one with 1 and one with -1. But you don't know which one. You can put both particles on other plantes, but as soon as you check the value on one, you also know the value of the other one. No information has been transported.
Also, in reality it's not value but something like spin or mass.
>Yeah but if you measure two entangled particles side by side that wouldn't help anything. You would have to measure them at a distance meaning sending the particle. There is no magical transport data across space. The "data" is the unmeasured value.
I don't think it works like that. it's like taking a dollar and putting it in a machine that rips it in half and packages both halves without showing which is which. You send the package somewhere and each package would contain different halves but you wouldn't know which half until you checked.
I'm probably an idiot but whatever
analogy is a sign of understanding. I didn't understand the analogy, but it definitely shows you have a concept. You smart bro, I just don't have the rules of the game yet to verify that you also know the rules to this game.
>Yeah but if you measure two entangled particles side by side that wouldn't help anything. You would have to measure them at a distance meaning sending the particle.
Having the particles far apart wouldn't help with anything either, because there is simply no way to make communication between entangled particles. You cannot control what state either particle will be in because the state is randomly decided whenever you look to see what it is.
Do you mean if you could somehow watch the particle's state constantly, rather than measure it once?
here is a popular explanation of entanglement
btw you probably would get more accurate answers if you asked /sci/, but they would also probably ridicule you
No, I believe we are on the same side of this. I was just trying to relate the idea to networking in the most plausible way which still doesn't work considering that even though you are sending a form of "data" it isn't usable in the way OP thinks.
The whole point of a quantum internet is the security. The idea is to make the data travel in such a way that intercepting it mid-flight will change or self destruct it, making it the ultimate in high-security transmission. It will be literally impossible to look at it undetected, because the very act of intercepting it modifies it in some way.
>Isn't this solved with direct fiber connections?
Understandable, I thought it was implied but I never would have thought about the possibility of interception. You wouldn't know if they matched without comparing them though, correct?
I believe there is already a quantom decryption algorithm:
Direct, overseas, without a single gateway between? Yeah, good luck.
You're right though, it'd require confirmation on both sides that they're entangled; but it doesn't really matter as entangled particles can convey no information.
I thought it was the...fuck I forgot what's it's called

Or something. Fuck. Do you know what I'm talking about? Different guy, btw. But I just read up on something about it
