I am not a physicist, but after reading the paper this seems like less of a breakthrough than they imply. Basically the process (as I understand it) is that they measure the energy state of qubit A, transmit that information to a different quantum computer containing qubit B, transmit the energy needed to excite qubit B into the same state as qubit A and finally exciting the qubit B into the same state as qubit A.

From the title, I was expecting some sort of an entangled energy transfer rather than what looks like an information transfer. This does not appear to be the case. Maybe someone who is more proficient in quantum physics can confirm if this is right.

I can't tell if they have done something really clever or really banal....I think they are saying that the energy is locked into a transfer between two entangled objects, but they I'm not sure they have distinguished between 'matched' and 'locked'. Hopefully someone smarter comes along and rescues us.

Isn't hyperbole a prerequisite of most science reporting?

Is that kind of quantum transfer of information instant? Wouldn’t that allow for faster-than-light communication?

No, nothing in quantum mechanics allows for FTP communication, full stop. If you ever find yourself asking this, you can safely assume the answer is ‘no’.

IceColdPorkSoda t1_j4ykm2p wrote

Doesn’t this also imply that qubit B would release an equivalent amount of energy when it relaxes? So if you had qubit on earth you could entangle them with qubits on mars, pump energy into the earth qubits and get energy release on mars?

i don't understand quantum physics nor the related maths (way way above my head currently); but science bitch §§§

Pretty useful for information transmission, energy & thermodynamics, space tech i guess (eh you can use a microwave using that fancy science to heat food without understanding precisely how everything works on theory side). And lotsa other topics

Negative energy? I could have shown them that for free

"observed negative energy" is actually a huge deal. AFAIK, it was previously effectively imaginary, since it requires temperatures below 0K. As mentioned elsewhere, it's the required piece for FTL.

guymine123 t1_j4ywea2 wrote

Not necessarily, the most up to date theory for a functional warp drive that doesn't use negative energy requires the mass-energy of the voyager 1 space probe to achieve FTL travel.

So just like in star trek, we're going to need a shit ton of antimatter to go warp speed.

U17sses t1_j4xyrjl wrote

no not yet, but I wouldn’t say never ppl can be quite pessimistic in that sense. no one denies that entanglement can “communicate” FTL but it’s the fact that no information can possibly be gleaned from entangled particles changing states because it’s random and cannot be meaningfully observed and assembled into coherent information, yet.

warplants t1_j4ycoh2 wrote

> no one denies that entanglement can “communicate” FTL

Wrong, plenty of physicists will deny this. Only certain interpretations of quantum mechanics rely on an FTL “wave function collapse” (namely, the Copenhagen interpretation, which at best is an incomplete description of reality, but more likely is just flat wrong.)

Yeah sorry I was busy when I wrote that, it’s more of a state of being that’s why I put communicate in quotes bc it’s not rly communicating it’s more just “being” that state.

Uhhhh, can't we already do these things? Teleportation is based off the word telephone, or vise versa, not sure dont care much, but that is energy teleportation, using wires, but so is induction. I'm not sure what is meant by negative energy, but light is energy, get your wavelengths right and it disappears, same with electricity, you can also use a vast majority of the EM spectrum to transmit energy, this is nothing new.

I have been wondering for some time what is so interesting about Quantum science, spent some time trying to figure it out, understand it, like fire and electricity (things I learned, not how to generate, but WHAT they are). It seems like hokey nonsense to me. I know there a major degrees awarded, and new discoveries made everyday, from dark matter, to dark energy, and they are spinning up particle accelerators with MeV's all the time, to try and understand it better. Here are some of my major issues, quantum behavior can be explained using EM, like induction. In theory, if you smash 2 protons together really hard, wouldnt you get a nuclear explosion? E=Mc^2, the difference in mass would be either the He formed, or the missing Proton, either way boom.

So why spend billions on paticle accelerators, I can tell you there is a reason, and I will not tell you what the reason is. So to be clear, Quantum seems hokey, particle accelerators are awesome and useful.

The device you're using to type this comment exists explicitly because of quantum mechanics. Modern chip fabrication exists due to discoveries related to quantum mechanics. It's far from hokey, it's responsible for most of our modern day technological existence.

You don't get to smartphones with pure old solid state electronics.

Interesting, I've heard from very few people that dual thread cores were the "original" quantum breakthrough, that tidbit was swept under the rug very quickly. Not sure why. At the same time cross processing multiple threads to speed things up isn't necessarily a Quantum behavior. Put the gates close enough together it could very easily be induction, the charge in one gate being the same (1 or 0 (think of it as + or negative) but the same) or not the same gives the three states you need to get some benefit to multiple thread resolution as the proposed "Quantum" effect you just mentioned. Lastly, thanks for keeping it real.

Buddahrific t1_j4wdvbb wrote

Dual thread cores have nothing to do with quantum mechanics (other than how they affect physics in general). It's just duplicating some resources that can't be shared and adding an identifier bit to the others that can be shared and taking advantage of instruction level parallelism mechanisms to execute instructions from two threads at once.

While some quantum mechanics effects are used in computing (eg flash memory uses quantum tunneling to write values into bits), quantum effects are more of a limiting factor for bleeding edge classical computing. Things are packed so closely together that it's difficult to prevent undesired quantum tunneling, which breaks the rules we normally associate with electrical circuits, like current preferring to flow through a conductive connection instead of through insulation protecting a nearby conductor.

Though, that said, the fact that we continue to make progress at the bleeding edge despite that implies that these quantum effects are becoming better understood and designs are at least compensating for them, if not outright taking advantage of them. But that's at a lower level than bigger features like hyperthreading.

Computers that use quantum effects at a higher level are called quantum computers.

Interesting so USB accidentally incorporates quantum tunneling, shame its not as fast as a USB upgrade, like 3.0 versus 2.0. The fact that it's accidental, and slower, means that it could just be a theory, and probably not a good way to understand it. Also you agreed with me on the multi thread thing. However Quantum computers using a multi position "gate/switch" don't exist, thats all I was trying to say. Another reply I recieved outlined a micrsoft language called Q, it is a service of Azure, and not an actual multi gate language. However, the probability of Azure creating a multi gate language is much higher than people doing it, but I don't think that's its purpose. More importantly, we need a stable processor, which nobody has, I mean how else are you gonna test it. As soon as you hear -273 degrees to gain function, you should grasp.... it's not gonna work. Again thanks for the reply.

Buddahrific t1_j4wmzmq wrote

That's flash storage that uses tunnelling, not USB. USB is just regular electric signals traveling along a conductor serially (as in one bit at a time and opposed to parallel, which would have multiple bits at a time).

Flash USB sticks are common, but you can have flash without USB and USB without flash. Flash is how it saves the data, USB is how the data is transferred between the storage and device using it.

LiCHtsLiCH t1_j4wq30g wrote

Yeah, I understood what you were saying. USB, is an interface, the rate at which data is transmitted is not effected by Quantum tunneling was my point. Last I checked nobody is building flash memory with special spacing or design to increase read and writes using this theory. Also, if it was used as a storage technique, you'd think it would have a different name, or a performance increase. Simply put, I'm not aware of this theory being used in any practical application... or any Quantum theory for that matter.

That statement right there u/LiCHtsLiCH is the linchpin. in which they're not talking about the transfer of quantum information as you stated is common but of quantum energy based on the first two paragraphs on the paper is a physical element.

Not aware of functional "Quantum" computers that use Qbits, instead of Si gates. So I have doubts IBM (or anyone) has one. There has been ZERO discussion relating to a programming language that can interact with that kind of processor. As far as Quantum as a whole, such as entanglement across distance in some sort of physics subspace sounds hilarious to me. The premise of Quantum as a science is that there are sub atomic paricles with varing rotations and orientations that effectively have 3 states of existence, and two of them we can't see or interact with. This is akin on some level to me, of 2/3 of my body not existing every once in a while based on un intentional change. Imagine getting accidently entageled with a star, a black hole or any celestial body, on accident, the results would be catastrophic. Ahkam's Razor, if we can do it on purpose, then it could happen accidentally, like climate change. People dont lose 2/3 of their mass periodically, nor have entageled on accident (get your head out of the gutter). Thanks for the break down on the article, I learned a while not to click on links i dont know, so I'm a bit hesitant. Lastly thanks for replying, I found this material super interesting, but could come up with easier methods of achieving the same behavior. A good read is a wiki on what started the pursuit of Quantum, something about a solar experiment in space that collected 1/3 as many nutrinos as expected, the obvious conclusion 2/3 were phasing in and out of existence?

If I was reading that correctly, it has nothing to do with Quantum computers. It appears to be Azure (machine learning suite) applied to multiple computers to self assess machine learning gains, this is right up IBM's alley.
