Researchers Achieve Quantum Teleportation Between Two Macroscopic Objects For The First Time

Sometimes it’s tough to get excited about stuff happening in quantum technologies, not because it’s anything less than fascinating but because it can be so hard to wrap your head around this stuff and anyhow the practical applications often seem very far away. But this is one of those milestones that you have to appreciate: Physicists have for the first time teleported quantum information from one macroscopic object to another. Researchers have been able to teleport quantum information for a while now. Quick quantum primer: This isn’t Star Trek-style teleportation, but the transfer of information--of quantum states--from one place to another without that information crossing the space between them in any way. This is achieved through the strange quantum phenomenon of entanglement, which allows two quantum objects to share the same quantum state such that if you influence one particle you also influence the other, whether they are separated by nanometers or light-years. RELATED ARTICLES As if Quantum Teleportation Weren't Spooky Enough, Physicists Propose 'Time Teleportation' FYI: How Quantum Teleportation Can Bring Us Secure Communications Researchers Achieve Quantum Teleportation Over 10 Miles of Empty Space TAGS Science, Clay Dillow, communications, physics, quantum internet, quantum physics, quantum teleportationSo by entangling two photons, for instance, physicists have demonstrated the ability to transmit quantum information from one place to another by encoding it in these quantum states--influence one of the pair and a change can be measured in the other without any information actually passing between the two. Researchers have done this before, between photons, between ions, and even between a macroscopic object and a microscopic object. But now Chinese researchers have, for the first time, achieved quantum teleportation between two macroscopic objects across nearly 500 feet using entangled photons. That’s pretty huge. The two bundles of rubidium atoms that served as sender and receiver are more or less analogs for what we hope will someday be our “quantum Internet”--a system of routers like the ones we have now that, instead of beaming information around a vast network of fiber optic wires, will send and receive information through entangled photons. So in a way, this is like a first proof of concept, evidence that the idea works at least in the lab. Now all we have to do is figure out is how to build several of these in series so they can actually pass information from one to the other. To do that, we only have to somehow force these quantum states to exist for longer than the hundred microseconds or so that they last now before degrading. Sounds easy enough.

Very interesting find, I have often said and pondered the world after we discover instantaneous data transmission technology.

Well it looks like soon we will be finding out, as this is the actual predecessor to "quantum internet".

Which is I believe the method employed by any interstellar races out there, as light speed communications are next to worthless.

What do you guys think about this?

www.popsci.com...

www.technologyreview.com...

So, when do we get to have instant realtime internet on alpha centuri?

Pretty cool potential..now lets make stuffs with that tech already! Seems already very usable if stable

-imagines a world with no ping-

Very cool. These are all just baby steps. I really wish I could be alive in 500 years. Our current time will be viewed almost like we view prehistoric man. The leaps we have made in 200 years are amazing. 500-1000 years down the line will be something to see. Too bad I won't see it. Thanks for posting!

Actually: Mass Effect (the game/book series) discusses this quite a bit.

How comm in space happens is, at least initially, there would be quantum bueys set around, connecting one to another for instant transfer of info...then you just get in range of one of these thingies and voila, you can communicate back to whereever (earth) instantly. It wasn't until later that there were installed versions on ships themselves, unfortunately, it wasn't a communicate anywhere, due to entanglement principles, you could only have it installed for a single point...such as only the office of whomever. So, it would probably not work like the internet anyhow verses channels on a tv you could swap over to (depending on how many quantum devices you had installed).

Still...pretty damn cool stuff. Amazing how our sci-fi films and such take place hundreds upon hundreds of years in the future and have tech that is literally a dozen or so years away...I think our vision is short sighted...

in the year 2500, we will have digital clocks on our wrists...wow!

I reckon by 2050, this world will be amazing, should moores law hold true.

there is speculation that this latest generation may birth the first immortals...now that would be neat.
Personally, I think they need to do a ton of research on cryonics...if death will be overcome shortly...would be nice if a placeholder was developed for those that may fall slightly short.

I totally agree! In the computer age, even light speed on earth isnt fast enough sometimes, not to mention the problems with signal interference that would be negated by the lack of a "transmission", as it uses entanglement instead of transmission.

This will totally redefine what data sharing is.

I wander if it is possible to monitor this????? I dont see how they could as there is no "signal" and it is straight P2P, instead of running through all the channels, as is the current standard.

I am very excited about this technology, it is kinda like the feeling I used to get at christmas as a child.

Saturn, you have a very unique and much appreciated, for my part, way of viewing all of this. Your comments mirror my thoughts very closely.

Mass effect..... just glorious reference, wanderful story, amazing games. Mass relays are after all, basically just teleportation, as they allow a ship to move many multiples of the speed of light, as the engines used to push around a thousands of tons ship, now push around a "weightless" ship.

No thanks are needed, it was my pleasure to share this with you all, this will be as important a step as say, fire, the wheel, steam power, flight...etc.

In the next 500 years, I dont think we will even be recognizable as a race any longer, as Saturn stated, if mores law holds.....well 500 years has comps that are trillions of times stronger than any human brain.

This is, i must say very very early on in this field........i wont be alive to see it."

Hmm..pretty cool.

Hey, if reverse time entanglement based communication is possible...maybe the WOW signal was a message from the future.

I bet we will know soon, if they dont already, as we are currently making leaps and bounds in this field, it is going to be a very interesting next 20 or 30 years in science I think.

This is more what I was discussing (not the relays as thats a whole different matter)


It takes on the issues with quantum communication also...
The codex discusses the tech further of course.

Good sci-fi uses cutting edge and foresight based on solid hypothetical science of the time.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today - but the core of science fiction, its essence has become crucial to our salvation if we are to be saved at all.

incidently, ME4 has been announced

I understood what you meant, I was simply throwing out the mass relays as a talking point on the matter.

Thanks for the video though, I love this game, I beat ME3 a couple of days. The kids were mad I was playing the Xbox everyday.

I wander what ME4 would be about, maybe shepard being in control of the reapers now?

Or what seems more likely to me, the geth knew about the "cycle', and so helped engineer all this, to get shepard to destroy the reaper army, breaking the cycle, and allowing them dominion over the weaker organics.

Time will tell though.

I hope the Geth aren't plotting, i quite like them...would hate to have to blow them to bits in ME4.

Donno. the only statements about it so far has been "It is not Shepherd, or Shepherd 2".
meaning it is a completely different story, no likeness, no crossing paths, etc...don't know if its a prequil, or a future..there is also the fact that the red ending (destruction) has been made canonical (official storyline). So, Shep is still alive (had to be done). Confirmed by Bioware.

But the no Shep or Shep 2 then makes one wonder where it will go from here...and what else will be made official (fate of the geth/quarians/krogan).
I don't mind it.. Mass Effect was meant to be a trilogy, and it was, and after some tweaking on the 3rd's ending, it was a good story. Any further titles should be seen as almost fanfiction based on a specific set of guides..happy with that actually, and hopefully they won't get themselves into too many plot hooks in the future (nightmare programming making later games suffer for it).
I, being a ME fanboy, am constantly trying to find out any new info about it...my dream would be bioware talk to bethesda for a new game (open world/space sandbox..skyrim in space...such dreams).

Totally off topic...sorry...just hit a interest point..and ME is currently carrying the "star trek/wars torch".

I had fun blowing them to bits in 1 and 2...meh...
But ya..they are better allies than enemys..and with the reapers destroyed, I don't think the corrupted code is a issue anymore.

I would think they will go in a new direction. I see a few possibilities...its ME, which means the threat needs to be terrifying and overwhelming on a galactic scale...
That leads me to think something like a galactic mass relay will be discovered (core of the galaxy, or in dark space where the reapers came from..a network connecting to different galaxys with terrible consequences)..or they could start up the initial idea of the dark energy(in ME2, you reunited with Tali who was studying a really strange sun being eaten up quickly by something called dark matter...this was meant to be the true threat, but since Karpyshyn was transferred to the star wars team, they nerfed it with just some erm..synthetic killing organics before synthetics can kill organics nonsense)

Now, this was meant to be the whole plot for ME3...but it was binned...
The issue I personally have with that one is that the moral choice at the end was...outstandingly dismal. Neverrmind losing Shepherd..imagine losing all of humanity..all of earth..to save the galaxy (the reason the reapers were interested in humanity is because our specific genetic structure was some sort of key..but it needed to basically destroy and assimilate all of humanity, all genetic code, to solve the dark energy issue that would destroy the entire universe in under 1k years)...What a horrible choice...you can choose to let the entire universe die..where the humans die..or you can sacrifice all humanity...so that the rest may live (yay if your a damn volus or whatnot..not so good if your a human).

To me, I am not even sure I would want to play such a game considering it would be an exercise in slow suicide

This is how time communication was invented. Prepare for the time line wars!

NA, just kidding. Would make for a great conspiracy theory.

This time Chinese scientists discover it before what will be the allied forces and they intercept a message about the exact location of an alien seed ship from our distant past full of exploitable tech.

OOOOH....

Well, this is a great find regardless of the sci fi twist.

EDIT:

Oh oh, and the alien seed ship, it is not an alien seed ship from the past, but a ship from OUR future, sent back to collect samples for our future since in the future we are colonizing mars after finally terra forming it, so we need a larger variety of fauna than what is left in the future. We look to our distant past to collect samples, but the expedition team is doomed. Then us in our present find the ship during a quantum entanglement experiment by picking up a signal from the ships emergency beacon which transmits using quantum entanglement of particles. Upon finding the ship we learn about time travel and set into motion a rip in the space time continuum and the ensuing paradox.

The war that ensues as each time line realizes what is happening is brutal. In one reality the Chinese have conquered their respective world and fight against the other realities where one group of forces fights to restore balance (led by the USA, of course). They cannot go back in time but must recruit more time lines into the fight as they suffer horrible losses from the future weapons. Each planet is then destroyed and their recruitment turns more into trans-time conquest.

The final battle sends a single American crew in the original recovered time ship back to the original moment when the future advanced people landed in the prehistoric past and promptly make them get the hell back into their ship and never mess with time again.

the end.

Oh, and then they get eaten by a dinosaur that originally killed the expedition team from the future....leaving their time ship in the exact location it was found, transmitting its emergency beacon where it will be found........today.......

Sorry about going way off topic btw.

On topic thought:

So, in say, 50 or so years, 3d printing will be where computers are now after 50 years of development (basic tic tac toe on a litebright style screen to living breathing worlds with stunning visuals).

Using quantum communications directing a advanced 3d printer (or metamaterials that form to shapes), one could speculate on not just instant communication, but instant replication of a object from across the world/galaxy...aka, telecommuting to work would be stepping into your room and a physical form appears at the other end of the communication point..a fully realized object in the form you have, even down to texture...

We can live in matrix pods then with a brain hookup...or walk into a toxic room with no issues as your really just sitting in your home perfectly safe as your avatar is on mars doing soil samples while wearing a wife beater t-shirt, etc..

ever feel like you were born a bit too early?

Damn man, I wish you would a few short stories in the short stories forums, that is a mind job, as now they would once again potentially recreate the exact same time paradox problems that had already been fixed........

Very nice, I like the way you think! Star for you.

No problems with being off topic in one of m threads, my ADD doesnt allow me to stay on topic even, as I was the one that first made basically an entire post that was off topic, cant help it as I love ME and your mentioning it was just too tempting to not talk about it further.
