Generation and confirmation of a (100x100)-dimensional entangled quantum system. arXiv (arXiv:1306.0096 [quant-ph]) / via Universitat Autònoma de Barcelona[/I] [quote=sciencedaily]An international team of researchers, directed by researchers from the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences, and with participation from the Universitat Autònoma de Barcelona, [B]has managed to create an entanglement of 103 dimensions with only two photons. The record had been established at 11 dimensions. The discovery could represent a great advance toward the construction of quantum computers with much higher processing speeds than current ones, and toward a better encryption of information.[/B] The states in which elementary particles, such as photons, can be found have properties which are beyond common sense. Superpositions are produced, such as the possibility of being in two places at once, which defies intuition. In addition, when two particles are entangled a connection is generated: measuring the state of one (whether they are in one place or another, or spinning one way or another, for example) affects the state of the other particle instantly, no matter how far away from each other they are. Scientists have spent years combining both properties to construct networks of entangled particles in a state of superposition. This in turn allows constructing quantum computers capable of operating at unimaginable speeds, encrypting information with total security and conducting experiments in quantum mechanics which would be impossible to carry out otherwise. Until now, in order to increase the "computing" capacity of these particle systems, scientists have mainly turned to increasing the number of entangled particles, each of them in a two-dimensional state of superposition: a qubit (the quantum equivalent to an information bit, but with values which can be 1, 0 or an overlap of both values). Using this method, scientists managed to entangle up to 14 particles, an authentic multitude given its experimental difficulty. The research team was directed by Anton Zeilinger and Mario Krenn from the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences. It included the participation of Marcus Huber, researcher from the Group of Quantum Information and Quantum Phenomena from the UAB Department of Physics, as well as visiting researcher at the Institute of Photonic Sciences (ICFO). The team has advanced one more step towards improving entangled quantum systems. [B]In a new article posted on arXiv, scientists described how they managed to achieve a quantum entanglement with a minimum of 103 dimensions with only two particles. "We have two Schrödinger cats which could be alive, dead, or in 101 other states simultaneously," Huber jokes, "plus, they are entangled in such a way that what happens to one immediately affects the other." The results implies a record in quantum entanglements of multiple dimensions with two particles, established until now at 11 dimensions.[/B][/quote] [url="http://www.sciencedaily.com/releases/2014/03/140327100612.htm"] More on this in the Source; including references[/url] As bill nye the science guy would say [img]http://www.reasonistproducts.com/wp-content/uploads/2013/08/bill-nye-science-rules-500.jpg[/img]

Uhhhh JohnnyMo help

science ppl of facepunch where are you when we need you

[QUOTE=Killer900;44383372]Uhhhh JohnnyMo help[/QUOTE]enlighten us o Emperor

ok

I understand everything but i'm not telling you

i've never understood this shcrodinger cat thingy no matter how hard i've tried is it even possible to understand quantum physics?

[QUOTE=Gurant;44383390]I understand everything but i'm not telling you[/QUOTE] selfish. hogging all the science and not sharing it with us laymen.

[QUOTE=UberMunchkin;44383388]What I can gather from my knowledge of Quantum Physics: Quantum Physics is complicated New things I learnt from this article: [B]Quantum Physics is more complicated now[/B][/QUOTE] You've now taken the first step towards Quantum Physics.. but there isn't really an end to the steps anyways In simple terms; if scientists can keep on this track of discoveries towards quantum computing, Computers of the future will be absolutely fucking amazing [QUOTE=Solidskei;44383448]The cat thing is a joke, read the last line.

The cat thing is a joke, read the last line. He's comparing the 2 particles used to 2 cats to simplify it. Atleast I think? He could also be using the cats as an example, I'm not certain.

[QUOTE=Solidskei;44383448]The cat thing is a joke, read the last line. He's comparing the 2 particles used to 2 cats to simplify it.[/QUOTE] okay but explain

mmm yes makes sense

[QUOTE=Saturn V;44383393] is it even possible to understand quantum physics?[/QUOTE] Quantum physics as a science is dedicated to trying to understand quantum physics.

I'll just turn off my brain and let the professionals handle it

[QUOTE=Hole;44383459]okay but explain[/QUOTE] [quote=phys.org]Instead of entangling many particles with a qubit of information each, scientists generated one single pair of entangled photons in which each could be in more than one hundred states, or in any of the superpositions of theses states; something much easier than entangling many particles. These highly complex states correspond to different modes in which photons may find themselves in, with a distribution of their characteristic phase, angular momentum and intensity for each mode. "This high dimension quantum entanglement offers great potential for quantum information applications. In cryptography, for example, our method would allow us to maintain the security of the information in realistic situations, with noise and interference. In addition, the discovery could facilitate the experimental development of quantum computers, since this would be an easier way of obtaining high dimensions of entanglement with few particles", explains UAB researcher Marcus Huber. Now that the results demonstrate that obtaining high dimension entanglements is accessible, scientists conclude in the article that the next step will be to search how they can experimentally control these hundreds of spatial modes of the photons in order to conduct quantum computer operations.

[QUOTE=Hole;44383459]okay but explain[/QUOTE] Instead of tangling multiple photons, they tangled 2 allowing them to find a minimum of 103 dimensions. Their states differ greatly in each dimension, like their intensities and etc. This is akin in a way to being dead or alive, states in which we reside. Each dimension is directly related, allowing for greater quantum computing capabilities. I think that's it?

This is the actual study made by the Scientists. read it if you dare [url]http://arxiv.org/ftp/arxiv/papers/1306/1306.0096.pdf[/url]

[QUOTE=Saturn V;44383393]i've never understood this shcrodinger cat thingy no matter how hard i've tried is it even possible to understand quantum physics?[/QUOTE] it was an inaccurate analogy to ridicule the current major interpretation of QM , it wasn't meant to be understandable [editline]28th March 2014[/editline] i get it now: before they could only make qubits hold 11 diff. states in a variety of super-positions, now they can do it with 103 which means a the photon-pair can hold a lot more information

[QUOTE=Hole;44383459]okay but explain[/QUOTE] it's a 'thought experiment' placing a cat in a situation triggerable by radiation (the decay of an atom). It draws a ridiculous example over what quantum physics dictates: that the cat exists in a '[url=http://en.wikipedia.org/wiki/Quantum_superposition]superposition[/url]- [quote]the idea holds that a physical system—such as an electron—exists partly in all its particular theoretically possible states (or, configuration of its properties) simultaneously; but when measured or observed, it gives a result corresponding to only one of the possible configurations[/quote] ultimately it asks "at what point does it stop being quantum entanglement" most people use schroedinger's cat in a simpler manner though, basically "you can't know the truth until you observe it"

I'm no expert, but I'm pretty sure that's akin to going from an alphabet of 11 letters to one with 103. Or a 11 based number system to a 103 based one. Think binary, to represent large numbers you need a longer strand of 1s and 0s than you would need using the regular 10 based number system. Or i guess you could use a specific set of 10 different states be one channel and have 10 channels to move information across. So, this means we can now transmit approximately 10 times more data per unit time than we could before. I'm pretty sure that's correct, but I'm certain someone here knows better.

This has inspired Disney's new animated feature film, "101 Dimensions". [QUOTE=Saturn V;44383393]i've never understood this shcrodinger cat thingy no matter how hard i've tried is it even possible to understand quantum physics?[/QUOTE] Good, that's the point. Quantum physics doesn't make sense. It's like if things exist in one state, exist in another state, exist in both states, and don't exist at all, all at once. It's some crazy shit.

i cant deal with this.

Don't worry guys I am sure Morgan Freeman will be here soon to explain everything.

johnny mo i summon thee, explain this bullshit

Equating binary systems with qubits and quantum computing is like trying to equate apples with oranges, they work in completely different ways. If you try to apply binary logic to quantum computing, your brain will hurt. Binary can only have two states, on and off. On the other hand, qubits (now according to this study) can have up to 101 states, allowing for some wizardy to happen that I don't quite understand. It basically just lets us store more information and process it faster. Edit: Although I could be completely wrong in my understanding, in which case you should take what I said with a grain of salt and study it yourself.

johnny mo! O great and powerful mod of the ages! I summon thee to explain thy physics bullshit!

We should call upon Avon instead, haven't seen him in a while.

Let me put this in computer terms: you have a 0 or a 1, these are two separate things, and either one or the other, but never both schrodinger's cat would be a 0 and/or a 1, they are two separate things, but the number might actually be the opposite (or the same) before you had 11 states, so 0 and/or anything up to and including 10, all separate bits of info but the actual number is any one of those 11 now you have 101 states, so 0 and/or anything up to and including 100, all separate bits of info but the actual number is any one of those 101 (Note: this doesn't include the other quantum stuff like things existing and then un-existing and then re-existing, or the states not ever being settled into a finite shape (so a 0 now != a 0 a moment later))
