Physicists Propose Scheme for Teleporting Light Beams

A little tangential thought: this is the sort of thing that would be "old-hat" to any technical civilization sufficiently long-lived to have begun to spread into their galaxy; this technology plus others, like high-temperature superconductivity plus genetic engineering (one would assume complete understanding and control over their own genome, probably for thousands of years) would be fully mature and maybe even obsolete. That is why it is so hard to imagine what a really advanced civilization would be like.

@retro: Yup, and that would mean there's what might be a very small window of "detectability" in the stages between intelligent life and what we'd consider an advanced civilization.

I maintain that it will not be we who detect such extraterrestrial civilizations, but they who will detect us, once we've made enough noise to be seen and/or heard.

Nothing new here. This ground has been covered.

new to me, first time I have seen it.

Searching the radio spectrum for ETs is like the Romans searching for ETs by looking for signal fires.

Capsules with entangled photon fields could ride the laser evacuated vacuum bubbles in the beams.. FTL transportation systems and tangible time travel in the next 5 years?

Nothing new here. This ground has been covered.

This statement seems unlikely to be true given what the researchers suggest in this article (though I have not yet read the paper - only it's abstract). It would appear that what is proposed is fundamentally different from teleporting the state of a single particle (akin to the difference between firing one electron in a cathode ray tube vs displaying a continuous TV signal). Can you provide some references to back your assertion?

Yes indeed, fundamentally different from teleporting the state of anything. It is about teleporting a "no light" state and therefore about transporting nothing and finding the same nothing. Anyone can take flights of fantasy and move combs of light but without experimental results and demonstrable verifiable predictions - worthless babble.

"Reducing matter to recorded light" that can be transported and re-assembled has been done, in part, by television. Real "transportation" would require, not "photons", but "electrons", on the theory that "All Matter Is Energy"!

Yes, it was called Wonkavision...

You know, I keep reading these articles trying to see some hint of how close they're getting to teleporting an apple across a city. But for the life of me, I can simply never understand exactly what it is they're talking about teleporting! Is it matter? Energy? Information? Near as I can understand, this experiment does not actually move particles across space; it merely copies their quantum state onto a set of similar particles waiting at some remote location. Is that correct? So it's only teleporting information. (Though the principle of interchangeability of particles might make this equivalent to actual particle transport.)

Valid questions from someone curious. You may profit from reading some good books on the subject if you like Physics.

Teleportation involves information, no matter is actually transfered.

third year university project proposals reaally should have some credability

It's a pop misnomer%u2014correlation, not teleportation which is tunnelling.



archonicus, shit-head: your -> you're; it's -> its



"antibunched"? Speak English: withbunched. "broad bandwidth"? Dolt.

What the hell are you talking about?

But information Teleportation would make matter.

This is absolutely incredible that they have at least figured out, in principle, how to design this experiment.

This might one day allow for incredibly useful deep space probes, and of course the benefits to networking and information technology here on earth are staggering. No more cable modem, just teleport the signal from computer to computer, instantly and with zero degredation.


This seems to be yet another case of Science Fiction predicting science fact (Star Wars and Star Trek Hypercom.)

'reproducing an infinity of (no light) states'?
(surely not easy!)

In quantum mechanics, all the forces of nature are mediated by the exchange of particles such as photons, and these particles must obey this cosmic speed limit. So an action "here" can cause no effect "over there" any sooner than it would take light to travel there in a vacuum.


But two entangled particles can appear to influence one another instantaneously, whether they're in the same room or at opposite ends of the Universe.


Einstein called this "spooky action at a distance" - spooky because there is no known mechanism for such an interaction, and because it would entail that things can be affected by events which, in some frame of reference, haven't happened yet.


Quantum entanglement occurs when two or more particles interact in a way that causes their fates to become linked: It becomes impossible to consider (or mathematically describe) each particle's condition independently of the others'. Collectively they constitute a single quantum state.


Austrian physicist Erwin Schrödinger in 1925 showed that if two particles are prepared in a quantum state such that there is a matching correlation between two "canonically conjugate" dynamical quantities %u2014 quantities like position and momentum whose values suffice to specify all the properties of a classical system %u2014 then there are infinitely many dynamical quantities of the two particles for which there exist similar matching correlations: every function of the canonically conjugate pair of the first particle matches with the same function of the canonically conjugate pair of the second particle.


Thus system No. 1 "does not only know these two answers but a vast number of others, and that with no mnemotechnical help whatsoever, at least with none that we know of."


Schrödinger coined the term "entanglement" to describe this peculiar connection between quantum systems:


When two systems, of which we know the states by their respective representatives, enter into temporary physical interaction due to known forces between them, and when after a time of mutual influence the systems separate again, then they can no longer be described in the same way as before by endowing each of them with a representative of its own. I would not call that one but rather the characteristic trait of quantum mechanics, the one that enforces its entire departure from classical lines of thought. By the interaction the two representatives [the quantum states] have become entangled.


Entangled Particles will entangle molecules continuously emitted (broadcast) non-locally and is received by and interacts with the other entangled particle pair's matter in its environment through a subtle process of exchange of quantum information. This is an extension of the known process of quantum emission/absorption and analogous to non-local quantum entanglement of the particle pairs matter.


Entangled Particle extends the reach of quantum physics beyond the atom and subatomic particles, but also into the larger world of encrypted data transmission. It brings the role of information in physical theories to the same level of importance as energy itself. Entangled Particle focuses not so much on particles as on the relationships and dynamic exchanges between energy, matter, photons, electric fields, and information. Entangled Particle looks into four basic quantum processes, heretofore largely ignored and left unexplored by science. They are as follows:


Entanglement:


The state or condition in which an enduring confluence occurs between atomic and subatomic particles during energy exchange or other processes, characterized by a commingling of particle attributes, such as spin, EMF, and quantum energy of shared interchange electrons in a persistent and congruent manner. Associated with entanglement is an instantaneous non-local, exchange of information through the use of atomic quantum correlation.


Coherence/Quantum Interference Correlation:


The observation made under experimental conditions that paired particles do not move or behave independently when involved in the same process or in energy transfers, as predicted by classical theory, but rather amalgamate in a sustained fashion and remain enjoined as an enduring discrete ensemble of particles with compatible spin and polarization characteristics, regardless of what paths, vectors or trajectories are adopted subsequently.

Non-Locality (near & far):


The omnipresent and omnidirectional transfer of influence at the quantum level instantly, simultaneously and ubiquitously, through wave-like or field-like resonance wherein spatial and temporal factors are inconsequential.


Interconnectedness:


The state of a universe that is considered to be unified and joined together holistically, through a process of non-local resonance occurring within the underlying zero-point field, that connects all matter, energy and information in the cosmos.


Entangled Particle suggests that all things in the universe are interconnected informationally. It also maintains that underlying this unity or oneness is the mystifying and mysterious dance between all matter and energy and information. Simply put, the basic promise of Entangled Particles is that the most profound insights about our universe will be discovered among the most subtle, implicit, and invisible phenomena of the sub-quantum level.


One result of Austrian investigators of the Institute of Experimental Physics of Vienna set a new record of teletransportation (Quantum Entanglement) of ' Photons crossed ' in the laboratory. The scientists had obtained quantum information from fiber glass of 800 meters of length, a canal of the Danube river the being crossed transversally and covering a distance of 600 meters, published in 20 of August in the scientific magazine British "Nature".

Teletransportation characteristics between two separate atoms, guided for university professor Anton Zeilinger, is based on the phenomenon of the ' Photons Entangled ' described by the Nobel Prize Albert Einstein as "Spooky effect at a distance".

One is about an effect of quantum mechanics that is not comparable with any phenomenon of the worlds current dimensions, since the two pair entangled photons, working in opposing directions, remain entangled between themselves.

Determining polarization of one of the photon, can be counted exactly on the other and has the same polarization, being identical of the first one. When transferring the quantum state exactly of a particle to another one, the scientists will have given a new step for teletransportation of substance. According to David Wineland, of the National Institute of Standards and Technology of Boulder, Colorado (U.S.A.), teletransportation of information between atoms is the key for powerful quantum computers, that must start to appear within one decade."

Aaaaaaaand the Naysayers will continue to say NO NO NO!!! No classical information can EVER be transmitted this way.... LONG after real communication devices have been built and are in use.... This is the EXACT hypothetical model of information exchange i have been TRYING fruitlessly to explain to my colleagues for YEARS now...

I guess they'll just have to create a new type of information that they feel CAN travel that way. hehe
