Quantum teleportation has taken another step forward, thanks to two complimentary experiments, one from ETH Zurich and one from the University of Tokyo. The researchers have demonstrated the most reliable yet version of quantum teleportation--what Nature is calling "quantum teleportation on demand."

Quantum teleportation has some pretty significant implications for communications; it works in a way not that dissimilar from the PGP-secured email we outlined here, except there's literally no physical link between the sender and receiver. (Read more about the implications for communications in Rebecca Boyle's excellent explainer.)

In the new experiments, conducted at the 100-micrometer scale and at temperatures of around 20 millikelvins, "Alice" and "Bob" from the example above are separated by about 5 mm. The University of Tokyo experiment managed to induce entanglement deterministically, which had only been done before at distances about 1,000 times smaller. And those previous experiments had only managed to do so reliably about 1 percent of the time, compared to this experiment, which teleported a qubit about 40 percent of the time (and reproduced it on the other end with about an 88 percent accuracy). So this is a huge leap forward!

Teleportation: Behind the Science of Quantum Computing
Researchers were able to reliably teleport information between quantum bits.

It might seem like something straight from the Star Trek universe, but two new research experiments—one involving a photon and the other involving a super-conducting circuit—have successfully demonstrated the teleportation of quantum bits.

If that sounds like gobbledygook, don't worry. We got in touch with one of the researchers, physicist Andreas Wallraff, of the Quantum Device Lab at the Swiss Federal Institute of Technology Zurich, to explain how his team and a team based at the University of Tokyo were able to reliably teleport quantum states from one place to another.

People have done this before but it hasn't necessarily been reliable. The new complementary research, which comes out in Nature today, is reliable—and therefore may have widespread applications in computing and cryptography.

2. Eurekalert: Teleported by electronic circuit

Teleported by electronic circuit
ETH-physicists 'beam' information

ETH-researchers cannot "beam" objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A to B – for the first time in an electronic circuit, similar to a computer chip.

Physicists at ETH Zurich have for the first time successfully teleported information in a so-called solid state system. The researchers did it by using a device similar to a conventional computer chip. The essential difference to a usual computer chip is that the information is not stored and processed based on the laws of classical physics, but on those of quantum physics. In a study, which is published in the current issue of the scientific journal Nature, the researchers were able to teleport information across a distance of about six millimeters, from one corner of a chip to the opposite one. This was shown to be possible without transporting the physical object carrying the information itself from the sender's to the receiver's corner.

"Usually, in telecommunication information is transmitted by electromagnetic pulses. In mobile communications, for example, microwave pulses are used, while in fiber connections it is optical pulses," explains Andreas Wallraff, Professor at the Department of Physics and head of the study. In contrast, quantum teleportation does not transport the information carrier itself, but only the information. This is possible due to the quantum mechanical properties of the system, in particular the entanglement established between the sender and the receiver. For non-physicists, entanglement constitutes a "magic" link between the two parties which exploits the laws of quantum physics.

4. That's great, but where the hell are my rocket cars and moving sidewalks? :)

Damn those early morning cartoons and my unrealistic expectations of the future!

I guess I'll just have to settle for boring old quantum teleportation.

[Scootaloo]

7. Ever been for a drive in Atlanta?

Would you want those fucks to be operating in three dimensions?

THAT'S why you don't have rocket cars

[cstanleytech]

8. That and the fuel costs dont forget. nt

[progressoid]

10. Hey, we got the "communicator"

And unlike the Star Trek version, ours can play Angry Birds!



Or try to find one of these on eBay:

36. Don't worry. You're not going to need either.

Press butan, arrive somewhere.

5. Very interesting!

[RKP5637]

6. Exceptionally interesting!

[Lucinda]

9. Bookmarking. TY!

[darkangel218]

11. I would like to see the aftermath of trying to teleport an animal!

It would be freakish looking

[tiny elvis]

14. 88 percent intact

about as good as a GMO

[darkangel218]

15. Yeeps!!

[Octafish]

30. Problems. Problems.

[FailureToCommunicate]

22. Michael Crichton called them "transcription errors"

deformities that build up over multiple quantum trips...

[HardTimes99]

31. Thereby explaining the mysterious origins of today's Republicans! :) - nt

[darkangel218]

32. Hahahahahaha!!

Right on!!

[kentauros]

37. Teb: But the animal is inside out.

Teb: And it exploded.

Jason Nesmith: Did I just hear that the animal turned inside out, and then it EXPLODED?

[MrScorpio]

12. Hopefully, none of those scientists are named Seth Brundle nt

[DeSwiss]

13. Fine.

I have a list here of people I'd like to have teleported, immediately. Pick any place you want, it doesn't matter.

- The sun! Yes, sending them to the sun would do.....

K&R

[burnodo]

16. a qubit?

what the hell is a qubit?

[Roland99]

17. Ask Bill Cosby!

[FiveGoodMen]

26. "Let's see... a qubit... I used to know what a qubit was... Well, never mind that..."

[Roland99]

18. BTW, the link in the OP is broken. It's incomplete. Here's a proper link >>>>

28. Thanks, fixed it. nt

[caseymoz]

19. Great. Now invent fusion power generation.

That's really the advance we need.

21. I demand that they immediately teleport

The Koch brothers to the dark side of the moon.

[Kablooie]

23. The "on demand" part it good. I hate it when out of the blue I'm teleported somewhere randomly.

[RushIsRot]

25. What about random teleportation out of the red?

[Javaman]

33. my check book could use that.

[PoliticAverse]

24. I don't want any quantums, when are they going to teleport pizza ? n/t

[RedCappedBandit]

27. Is such a thing even possible?

[FrodosPet]

29. But can they teleport blueberry pie?

[jakeXT]

34. Uhura and her pointy things....lol /nt

[BootinUp]

35. 88 percent accuracy? Fortunately it didn't live long, lol.

[live love laugh]

38. This went over my head fast enough to break the sound barrier. WTH are they talking about?

I know what teleportation is but the rest...
