Room Temperature Quantum Entanglement in Semiconductor

originally posted by: MystikMushroom
I wonder if a set of identical clones could be "entangled"....

Hm....

You know there's websites for that?

As for the op....That's pretty damn cool (pun intended).
One question though, is that room temperature at full operation or idling?

We are very close to being able to purchase quantum based NICs, just a matter of time. We still need a good quantum network protocol that actually works however.

Good thing you asked! This was released yesterday!

They use laser to create a key-coded interference pattern (like the particle-wave double slit experiment) then transmit the pattern off to the recipient that will check the quantum key during the "hand-shake" before accepting the data stream! Seems like it would almost be easier to encode the key into the chip itself so only quantum chips can talk on certain networks. But that gets back to the "haves" and the "have nots" which the whole internet is supposed to make level.

You know I was wondering the same thing. What is the heat tolerance or variance allowed since it was not stated in the article. Almost all pieces of equipment have temperature ranges they are constructed to operate in so what is their top end? IDK. Does chip cooling affect this effect? Again, IDK.

Ooohh! Did not even get to thinking about SQUIDs! Are real life Tricorders around the corner? "Dammit he's dead Jim!"

And I think it would the opposite for the antenna--smaller. Did you know they used fractals to create antennas internally (notice how cell phones no longer have the "whip" at one end?).

Quantum fractals, now there is an idea!

a reply to: TEOTWAWKIAIFF

That's actually a very honest answer. Kudos

I don't think they really know either. They might have a rough guess, but it's still relatively new tech, so only time will tell I guess.

For the normal average user, it´s a little bit complicated but just because almost everyone has used windows prior to linux. Back then, in dos times, it would not make any difference. Don´t forget, what you see on your screen is just a GUI, a frontend for the user to interact with the system. You can create folders with your mouse, by shortcut, all on the gui, or you can open a shell/cmd and do it there. Sometimes a shell is faster and not every tool has a fancy GUI.
Because often it does not make sense at all to waste time on that.

I wouldn't underestimate the usefulness of a GUI though. It eliminates the need to know all variable names or commands and the specific syntax. So as a user you can get to the business of doing things rather than trying to figure out what the command name is, and in what specific order things have to be typed out. If the GUI is any good, it will also prevent you from performing invalid operations. GUI's get over a rather big hurldle in usability, of course many Linux people with years of dealing with the intracacies of using a language don't grep that. (However it has improved significantly in the last decade, as people coming in have grown up on OS's with GUIs and understand why they're good if implemented correctly.)

This is also the same reason why it's way way easier to program visually with a node diagram. (Many softwares for stuff like sound-design or 3D art have this method implemented, to hide the fact you're programming those things from the user.) All the building blocks are on the table, and if you make spaghetti code it really does look that way. It also gives much better cues to what related things can and should be grouped together into modular functions.

Ahh... I suppose that's almost too far off-topic. But I suppose faster computer architectures which come out of this technology will increase power available for emulation or compilers. So those visual interfaces will become more predominant in relation to stuff that was considered more "bare-metal" and previously abstract-seeming, like machine code. (Will always have it's use though, but becoming even more of a black art.)

Yeah pick up a clean wifi signal WITH ONE MICROWAVE PHOTON!

Normal wireless antenna amp gain: 10-50dB(10-100,000 times higher amplification)

SQUID amplified Wifi signal gain: Trillions of times higher(only one photon is needed)?
I am not a physicist,engineer, or an expert on this but can't you detect a Wifi hotspot from the surface of Mars with a SQUID antenna?

Star Trek enterprise-style long range scanners?(There are humanoid lifeforms detected on Beta Quadrant Z)

So, I thought "quantum fractals" would be cool and neat except it has already been considered!

Here, Benedetti considers two types of spacetime with quantum group symmetry - a quantum sphere and k-Minkowski spacetime - and calculates their dimensions. In both spaces, the dimensions have fractal properties at small scales, and only reach classical values at large scales.

The idea works out to be a pretty representative of the real world. Hey, the math works out so it must be accurate at some level!

a reply to: pauljs75

I hear you! But since there are now touch screens the GUI will be here for a while. There's your new tech term: quantum GUI!! "I see here (points at resume) that you have three years experience as a quantum GUI programmer..." hehehe.

Programming is not too far off target! I am not sure how much a normal person would need to understand how quantum computers actually work to get benefits from the tech. Which is funny I am saying that. Check this out.

Phys.org, April 17, 2016 - Take that, A.I.: Video-gamers solve quantum physics mystery using human intuition

So by representing a "real world" quantum problem as a simple computer game, the gamers were able to figure out several strategies to "win" the game. What they really did was demonstrate solutions to the quantum world problem that physicists were not sure was solvable!

More kicks from Universe trying to see if I'm paying attention!

[Erwin Schrodinger] realised that you can’t describe electrons or atoms or any of the other smallest pieces of the Universe as billiard balls that will be exactly where you expect them to be exactly when you expect them to be there.

Instead, you have to assume that particles have positions that are spread out in space, and that they only have some probability of appearing where you think they’re going to be at any point in time. If you work with spread-out probabilities instead of with specific positions, you can exactly predict the results of a bunch of experiments that puzzled physicists at the beginning of the 20th century.

Schrödinger’s equation tells you the relationship between how these probabilities change in time and the way they change in space. Working with probabilities instead of positions might be weird, but it works.

[F]ish generally move as a single group, with a bunch of individuals moving around pretty randomly within it. Every once in a while, a fish might see a piece of food away from everyone else, and swim over on its own to grab it, before swimming back to its school for safety.
...
The probability of finding a fish [in the school of fish] could have evolved in any number of complicated ways with equations that had never before been written down. But it doesn’t. The probability of finding a fish changes exactly like the probability of finding an electron does. The fish follow Schrödinger’s equation [the team reports]

Source: ScienceAlet.com - Quantum physics has just been found hiding in one of the most important mathematical models of all time

So they were thinking of a school of fish using "mean-field" game theory which borrows the name from physics where that theory is used to model a bunch of particles where the individual particle does not impact the larger group. The math in game theory model could be stated but it was thought to be a massive under taking to solve all possibilities. Now they can use the Schrodinger equation to get the same results! Their thinking is that some of the open-ended math problems can be re-stated as a quantum mechanics problem and use the Schrodinger equation to provide an answer!

This is a weird loop! Things like this always start happening when I look at quantum mechanics. Human intuition about playing a video game and a school of fish all tied in with the quantum world. What does the probability drive read?

Graphene will be the next step cranking up the rate of cycle on microcontrollers and CPUs.
The last ten years, the way was to go parallel, meaning more cores and caches.
With graphene, we´ll be able to unlock the 100Ghz barrier pretty fast and who knows where it ends.

There is a nice article out there how the industry made moores law self fulfilling but slowly comes to a stop.
I found it but it´s not in english.

Have you managed to find out about idle temps vs active temps?

I've been searching and not found anything conclusive yet. Found a lot of speculation though.

I just want to know if I'd be able to run a high end game, say Crysis 43 (probably be that long before they're commercial products lol) without the risk of burning down my country lol.

a reply to: TerryDon79

Not a word (yet). If I do find out I will post an update (kinda wanna know myself!)

Another break through in quantum computing.

The perfect state transfer has emerged as a promising technique for data routing in large-scale quantum computers," Peruzzo said.

"The last 10 years has seen a wealth of theoretical proposals but until now it has never been experimentally realised.

"Our device uses highly optimised quantum tunnelling to relocate qubits between distant sites.

"It's a breakthrough that has the potential to open up quantum computing in the near future."

Source: ScienceDaily.com - Quantum computing closer as scientists drive towards first quantum data bus

This involved several research teams from Australia, Italy, and China. Moving q-bit data is a difficult task as exemplified by using a computer game to simulate the problem (previously posted).

Only missing item is storage. There was a crystal storage device that could encode exobytes (or was it yottabytes?). Maybe we can now see Mystik's holographic memory storage device? And yes, TerryDon, an epic game of Crysis 43 would be called for!

a reply to: TEOTWAWKIAIFF

Storage might be the biggest problem depending on the size of data interpretation on a quantum computer. What's 1GB on a regular PC might be more/less on a quantum PC.

I like the idea of holographic storage, but what happens if the electric goes out? Wouldn't that stop the hologram, therefore losing all data?

a reply to: TerryDon79

I was not thinking of the actual interaction of light creating a storage medium (like the chess guys in Star Wars)! Cool idea until you lose power.

3D storage using holograms would be doable as a "write once read many" type device. The idea is to "burn" patterns and error correcting and datum itself on one pass to some medium. A secondary reader reconstructs the hologram encoded information. It is still the same idea as cd-rom but the "what + how" it is written then reconstructed differs because you are not just getting back "0" or "1" but a string of information (you could probably even encode pass keys into it).

Since light is limited only by the wavelength involved the amount of data increases the shorter the wavelength. So massive amounts of data can be stored on a dvd sized storage medium. Since quantum computer would have millions of qubits they would, probably (actually guessing here), need massive storage.

Maybe that means if quantum computing does come online then EVERYTHING AFTER will always be available?

a reply to: TEOTWAWKIAIFF

That's some fair points.

I didn't think of it that way. I think my way of thinking of holograms was too basic a definition.

I think that once quantum computing has been made an feasible it will be like the first single chip computer. Then we had the advent of dual cores, quad cores and so on.

D'oh! In my list above and discussion on memory, forgot about the most important part of computing: logic gates.

At present, even small and medium scale quantum computer circuits cannot be produced because of the requirement to integrate so many of these gates into the circuits. One example is the Fredkin (controlled- SWAP) gate. This is a gate where two qubits are swapped depending on the value of the third.

Usually the Fredkin gate requires implementing a circuit of five logic operations. The research team used the quantum entanglement of photons—particles of light—to implement the controlled-SWAP operation directly.
...
The quantum Fredkin gate can also be used to perform a direct comparison of two sets of qubits (quantum bits) to determine whether they are the same or not. This is not only useful in computing but is an essential feature of some secure quantum communication protocols where the goal is to verify that two strings, or digital signatures, are the same," said Professor Tim Ralph from the University of Queensland.

Source: Phys.org - Physicists demonstrate a quantum Fredkin gate

Creating qubits is tough enough but logic gates? Feel kind of stupid on that one (shakes head ruefully). Science to the recue! And so creative to do it directly using a property of the quantum world!

Terry, sorry my man, we agree on disagree! The actual paper does not state the operational characteristics of the device they made. Just that they ran it at 296 Kelvin (73 F, or room temperature). (TD, saw that--agree...--on another thread and thought it was funny! Not meant as being mean)

The researchers used infrared laser light to order (preferentially align) the magnetic states of thousands of electrons and nuclei and then electromagnetic pulses, similar to those used for conventional magnetic resonance imaging (MRI), to entangle them. This procedure caused pairs of electrons and nuclei in a macroscopic 40 micrometer-cubed volume (the volume of a red blood cell) of the semiconductor SiC to become entangled.

Phys.org - same link as OP - Quantum entanglement achieved at room temperature

The "typical of an MRI" is not a value! Here are some comparisons of magnetic field strengths that I know.

So, a typical MRI runs at around 9 Tesla. They're containing the Wendelstein 7-X plasma at 3 T (same as the LHC). They levitated the frog at 12 T. And MIT upgraded their ARC Fusion device with REBCO super conducting magnets creating a 14 T field and thereby reducing their reactor foot print because as magnetic strength increase it scales to the fourth power as applied to plasma containment (think that is right).

Unknown is the range above room temperature this works. They did note that it also works if cooled and their ideas for using such a device with "superconducting resonators" and optical fields (no further elaboration). The original article doesn't state they had to create an imaging device to check for entanglement! They also created their own logic gates and registers to demonstrate QE (flip the state of a register, show the entangled one also flips by the same amount and spin direction).

Hope everybody here finds this additional information useful! (Reading computer logic and QM in the same paper is a mind roller coaster!)
