I thought hamradio might get a kick out of this. Ham's been missing since May 14.. jamesjazz since April 20..  OMG! One of us is next! It's the 62 Little Indians scenario. I guess I'll have to start sleeping with my eyes open. Well, ham.. maybe you're out there in read-only mode and can still enjoy this link.

Scientists Report Finding Reliable Way to Teleport Data
 

Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”

In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.

 

Quantum teleportation is not the “Star Trek”-style movement of people or things; rather, it involves transferring so-called quantum information — in this case what is known as the spin state of an electron — from one place to another without moving the physical matter to which the information is attached.

 

Classical bits, the basic units of information in computing, can have only one of two values — either 0 or 1. But quantum bits, or qubits, can simultaneously describe many values. They hold out both the possibility of a new generation of faster computing systems and the ability to create completely secure communication networks. Moreover, the scientists are now closer to definitively proving Einstein wrong in his early disbelief in the notion of entanglement, in which particles separated by light-years can still appear to remain connected, with the state of one particle instantaneously affecting the state of another.

 

They report that they have achieved perfectly accurate teleportation of quantum information over short distances. They are now seeking to repeat their experiment over the distance of more than a kilometer. If they are able to repeatedly show that entanglement works at this distance, it will be a definitive demonstration of the entanglement phenomenon and quantum mechanical theory.

 

Succeeding at greater distances will offer an affirmative solution to a thought experiment known as Bell’s theorem, proposed in 1964 by the Irish physicist John Stewart Bell as a method for determining whether particles connected via quantum entanglement communicate information faster than the speed of light.

 

“There is a big race going on between five or six groups to prove Einstein wrong,” said Ronald Hanson, a physicist who leads the group at Delft. “There is one very big fish.” In the past, scientists have made halting gains in teleporting quantum information, a feat that is achieved by forcing physically separated quantum bits into an entangled state. But reliability of quantum teleportation has been elusive. For example, in 2009, University of Maryland physicists demonstrated the transfer of quantum information, but only one of every 100 million attempts succeeded, meaning that transferring a single bit of quantum information required roughly 10 minutes.

 

In contrast, the scientists at Delft have achieved the ability “deterministically,” meaning they can now teleport the quantum state of two entangled electrons accurately 100 percent of the time. They did so by producing qubits using electrons trapped in diamonds at extremely low temperatures. According to Dr. Hanson, the diamonds effectively create “miniprisons” in which the electrons were held. The researchers were able to establish a spin, or value, for electrons, and then read the value reliably. In addition to the possibility of an impregnable quantum Internet, the research holds out the possibility of networks of quantum computers.

 

To date, practical quantum computers, which could solve certain classes of problems far more quickly than even the most powerful computers now in use, remain a distant goal. A functional quantum computer would need to entangle a large number of qubits and maintain that entangled state for relatively long periods, something that has so far not been achieved.

 

A distributed quantum network might also offer new forms of privacy, Dr. Hanson suggested. Such a network would make it possible for a remote user to perform a quantum calculation on a server, while at the same time making it impossible for the operator of the server to determine the nature of the calculation.

Stop it. You just stop it, now! STOP!

 

Scientists Bring Light to Full Stop, Hold It, Then Send It on Its Way
 
By JAMES GLANZ
Published: January 18, 2001
 
Researchers say they have slowed light to a dead stop, stored it and then released it as if it were an ordinary material particle.
 
The achievement is a landmark feat that, by reining in nature's swiftest and most ethereal form of energy for the first time, could help realize what are now theoretical concepts for vastly increasing the speed of computers and the security of communications.
 
Two independent teams of physicists have achieved the result, one led by Dr. Lene Vestergaard Hau of Harvard University and the Rowland Institute for Science in Cambridge, Mass., and the other by Dr. Ronald L. Walsworth and Dr. Mikhail D. Lukin of the Harvard-Smithsonian Center for Astrophysics, also in Cambridge.
 
Light normally moves through space at 186,000 miles a second. Ordinary transparent media like water, glass and crystal slow light slightly, an effect that causes the bending of light rays that allows lenses to focus images and prisms to produce spectra.
 
Using a distantly related but much more powerful effect, the Walsworth-Lukin team first slowed and then stopped the light in a medium that consisted of specially prepared containers of gas. In this medium, the light became fainter and fainter as it slowed and then stopped. By flashing a second light through the gas, the team could essentially revive the original beam.
 
The beam then left the chamber carrying nearly the same shape, intensity and other properties it had when it entered. The experiments led by Dr. Hau achieved similar results with closely related techniques.
 
''Essentially, the light becomes stuck in the medium, and it can't get out until the experimenters say so,'' said Dr. Seth Lloyd, an associate professor of mechanical engineering at the Massachusetts Institute of Technology who is familiar with the work.
 
Dr. Lloyd added, ''Who ever thought that you could make light stand still?''
 
He said the work's biggest impact could come in futuristic technologies called quantum computing and quantum communication. Both concepts rely heavily on the ability of light to carry so-called quantum information, involving particles that can exist in many places or states at once.
 
Quantum computers could crank through certain operations vastly faster than existing machines; quantum commmunications could never be eavesdropped upon. For both these systems, light is needed to form large networks of computers. But those connections are difficult without temporary storage of light, a problem that the new work could help solve.
 
A paper by Dr. Walsworth, Dr. Lukin and three collaborators -- Dr. David Phillips, Annet Fleischhauer and Dr. Alois Mair, all at Harvard-Smithsonian -- is scheduled to appear in the Jan. 29 issue of Physical Review Letters.
 
Citing restrictions imposed by the journal Nature, where her report is to appear, Dr. Hau refused to discuss her work in detail.
 
Two years ago, however, Nature published Dr. Hau's description of work in which she slowed light to about 38 miles an hour in a system involving beams of light shone through a chilled sodium gas.
 
Dr. Walsworth and Dr. Lukin mentioned Dr. Hau's new work in their paper, saying she achieved her latest results using a similarly chilled gas. Dr. Lukin cited her earlier work, which Dr. Hau produced in collaboration with Dr. Stephen Harris of Stanford University, as the inspiration for the new experiments.
 
Those experiments take the next step, stopping the light's propagation completely.
 
''We've been able to hold it there and just let it go, and what comes out is the same as what we sent in,'' Dr. Walsworth said. ''So it's like a freeze frame.''
 
Dr. Walsworth, Dr. Lukin and their team slowed light in a gas form of rubidium, an alkaline metal element.
 
The deceleration of the light in the rubidium differed in several ways from how light slows through an ordinary lens. For one thing, the light dimmed as it slowed through the rubidium.
 
Another change involved the behavior of atoms in the gas, which developed a sort of impression of the slowing wave.
 
This impression, actually consisting of patterns in a property of the atoms called their spin, was a kind of record of the light's passing and was enough to allow the experimenters to revive or reconstitute the original beam.
 
Both Dr. Hau's original experiments on slowing light, and the new ones on stopping it, rely on a complex phenomenon in certain gases called electromagnetically induced transparency, or E.I.T.
 
This property allows certain gases, like rubidium, that are normally opaque to become transparent when specially treated.
 
For example, rubidium would normally absorb the dark red laser light used by Dr. Walsworth and his colleagues, because rubidium atoms are easily excited by the frequency of that light.
 
But by shining a second laser, with a slightly different frequency, through the gas, the researchers rendered it transparent.
 
The reason is that the two lasers create the sort of ''beat frequency'' that occurs when two tuning forks simultaneously sound slightly different notes.
 
The gas does not easily absorb that frequency, so it allows the light to pass through it; that is, the gas becomes transparent.
 
But another property of the atoms, called their spin, is still sensitive to the new frequency. Atoms do not actually spin but the property is a quantum-mechanical effect analagous to a tiny bar magnet that can be twisted by the light.
 
As the light passes through, it alters those spins, in effect flipping them. Though the gas remains transparent, the interaction serves as a friction or weight on the light, slowing it.
 
Using that technique, Dr. Hau and Dr. Harris in the earlier experiment slowed light to a crawl. But they could not stop it, because the transparent ''window'' in the gas became increasingly narrower, and more difficult to pass through, as the light moved slower and slower.
 
In a recent theoretical advance, Dr. Lukin, with Dr. Suzanne Yelin of Harvard-Smithsonian and Dr. Michael Fleischhauer of the University of Kaiserslautern in Germany, discovered a way around this constraint.
 
They suggested waiting for the beam to enter the gas container, then smoothly reducing the intensity of the second beam.
 
The three physicists calculated that this procedure would narrow the window, slowing the first beam, but also ''tune'' the system so that the beam always passes through.
 
The first beam, they theorized, should slow to an infinitesimally slow speed, finally present only as an imprint on the spins, with no visible light remaining. Turning the second beam back on, they speculated, should reconstitute the first beam.
 
The new experiments bore those ideas out.
 
''The light is actually brought to a stop and stored completely in the atoms,'' Dr. Harris said. ''There's no other way to do that. It's been done -- done very convincingly, and beautifully.''
 
Chart: ''THE BASICS: Holding Light Still'' Physicists say they have found a way to slow light to a stop. THE PROCESS (SCHEMATIC) Two beams of light strike a vapor of rubidium atoms, altering them so they do not absorb light as they normally would. This allows the first beam to imprint a pattern in their spin orientation. As the second beam is turned down, the first beam slows to a halt and virtually diasappears as it labors to alter the atoms' spin patterns. The first beam can then be released as the second beam is turned back up. (Source: Dr. Ronald L. Walsworth Harvard-Smithsonian Center for Astrophysics)(pg. A21)

If you ain't careful, Kid, this is going to wind up being a self-perpetuated thread, much like Jake's "Dog's Life" thread.

I'm like the old lady on the ESURANCE commercial---I don't know how any of this works.  I can't watch any "internet television" on my main set, and if I get this right, I resent the possibility of being forced into buying "devices" that would make it possible.  I understand newer TVs are being made with this capability built-in, but Idon't notice anyone pulling out their wallets to help provide me with one.  I already dealt with this sort of crap in the "vinyl-to-CD" conversion and the "tape-to-DVD" conversion.  I guess this is my punishment for NOT drinking the tech-Kool-Ade.

I've always supported the "a la carte" system of cable/satellite subscription. This doesn't exist (yet), but I support it. Just give me a price-per-item-per-month service and let me choose my own programming from your entire catalog - period.

 

My new LCD tv is not a "smart" tv with internet, but it does have HD connections for use as a second monitor - that is all I require.

Funny, Kid, but I was just thinking about that last night!  Good name, "Ala Carte" TV.  My Idea was that customers pay a modest monthly fee to recieve only the channels they watch the most, with a sort of "OnDemand" menu available to tune in to channels they might find something they wish to view only occasionally.

Just heard this in the opening scenes of The Boy and the Pirates (1960) - now on TCM

 

The whole kit and caboodle

 

Meaning:

 

A collection of things.

 

Origin

 

The words kit and caboodle have rather similar meanings.

 

A kit - is set of objects, as in a toolkit, or what a soldier would put in his kit-bag.

 

A caboodle (or boodle) - is an archaic term meaning group or collection, usually of people.

 

There are several phrases similar to the whole kit and caboodle, which is first recorded in that form in 1884. Most of them are of US origin and all the early citations are American. Caboodle was never in common use outside the USA and now has died out everywhere, apart from its use in this phrase.

 

- The whole kit - the whole of a soldier's necessaries, the contents of his knapsack. From Grose’s Dictionary of the Vulgar Tongue, 1785.

 

- The whole kit and boodle

 

Although this citation is slightly later than that of the final 'whole kit and caboodle', it's worth including as it gives a 19th-century version of the meaning of the term. It may still be a step along the way - either unrecorded before 1888 or recorded in an, as yet, undiscovered work. This piece, titled 'The Origin of Boodle', is from The Dunkirk Observer-Journal, New York, September 1888:

 

"It is probably derived from the Old-English word bottel, a bunch or a bundle, as a bottel of straw. "The whole kit and boodle of them" is a New England expression in common use, and the word in this sense means the whole lot. Latterly, boodle has come to be somewhat synonymous with the word pile, the term in use at the gaming table, and signifying a quantity of money. In the gaming sense, when a man has "lost his boodle", he has lost his pile or whole lot of money, whatever amount he happened to have with him."

 

- The whole kit and boiling (or bilin')

 

Sinclair Lewis, in 'Main Street', 1920:

 

"...and some of these college professors are just about as bad, the whole kit and bilin' of 'em are nothing in God's world but socialism in disguise!"

 

- The whole (or whool) boodle

 

From J. Neal's, 'Down-Easters', 1833:

 

"I know a feller 'twould whip the whool boodle of 'em an' give 'em six."

 

From Bangor Daily Whig And Courier, Maine, 1839:

 

"A whole squad have got to permit to see you.

Who are they?

I don't know, a whole boodle of them."

 

- The whole caboodle

 

From the Ohio State Journal, 1848:

 

"The whole caboodle will act upon the recommendation of the Ohio Sun."

 

Which brings us finally to the whole kit and caboodle

 

From the Syracuse Sunday Standard, New York, Nov, 1884:

 

"More audiences have been disappointed by him and by the whole kit-and-caboodle of his rivals."

 

It is most likely that these phrases were in use simultaneously and that there isn't a clear parentage of one to another. 'Kit and caboodle' had the advantage of the alliterative 'k' sound and that's doubtless why it has outlasted the others, which are now all fallen out of use.

 

What we can't confirm is that the word caboodle migrated from boodle in order to sound better when matched with kit. It is possible that that's what happened, but the dates of the known citations don't support it. Whole kit and caboodle, (1884) is recorded before whole kit and boodle, (1888) and whole caboodle comes well before both, in 1848. Perhaps that's just the inadequacy or either records or research and that citations with the appropriate dates will emerge later.
