Researchers Send Information Using a Single Particle of Light (vice.com)
An anonymous reader quotes a report from Motherboard: According to research published Thursday in Science, physicists at Princeton University have designed a device that allows a single electron to pass its quantum information to a photon in what could be a big breakthrough for silicon-based quantum computers. The device designed by the Princeton researchers is the result of five years of research and works by trapping an electron and a photon within a device built by HRL laboratories, which is owned by Boeing and General Motors. It is a semi-conductor chip made from layers of silicon and silicon-germanium, materials that are inexpensive and already widely deployed in consumer electronics. Across the top of this wafer of silicon layers were laid a number of nanowires, each smaller than the width of a human hair, which were used to deliver energy to the chip. This energy allowed the researchers to trap an electron in between the silicon layers of the chip in microstructures known as quantum dots. The researchers settled on photons as the medium of exchange between electrons since they are less sensitive to disruption from their environment and could potentially be used to carry quantum information between quantum chips, rather than within the circuits on a single quantum chip. The ability to scale up this device would mean that photons could be used to pass quantum information from electron to electron in order to form the circuits for a quantum computer. "We now have the ability to actually transmit the quantum state to a photon," said Xiao Mi, a graduate student in Princeton's Department of Physics. "This has never been done before in a semiconductor device because the quantum state was lost before it could transfer its information."
God bless all of you! To those of different beliefs, the best to you as well!
Wow! I guess it's safe to say for once that this is a real quantum leap!
You're an asshole. Go fuck yourself.
No matter what, the researchers keep finding that the one piece of information sent is always 42 for some reason.
"Liberalism is a very noble idea, currently controlled by some very bad people. Be sure you do not get the two confused.
So you just joined GNAA?
I have a chocolate machine, it has two independant parameters, they are completely random and unconnected: a) Dark, Milk, or White chocolate. b) Hazelnuts, raisins, or brazil nuts.
At any time, I will get a random type of chocolate, sometimes dark, sometimes milk, sometimes white, with no descernable pattern . At any time I will get a random filling, sometimes, hazelnuts, raisins or even brazil nuts. The nut filling does not correlate to the chocolate type, or visa versa and neither correlates to time.
Fragments of chocolate shoot everywhere, some of it is in superimposition state, it has no specific nut or chocolate type until we measure it. Only then does it set the chocolate type and filling. Now you might find that hard to believe, if we detected brazil nuts, and the bar became brazil nut, then the brazil hopper at an earlier time must have fewer nuts, and the truck delivering the brazil nuts must have arrived a little earlier to keep it topped up. This is what happens, the effects ripple backwards in time and across infinite space, as this bar goes from superimposition bar to a known bar of chocolate.
We call this Wonker Special Christmas Chocolate.
If we break up chocolate on a conveyor belt, take multiple fragments off the conveyor belt*, we can measure one fragment and by spooky distance effect, the other entangled fragments are also the same filling and chocolate type! Now we could Fedex this entangled chocolate across the world, and when one of us measures the chocolate type, the other pieces will be magically set at the same time by spooky distance effect. Sending information faster than light.
We can even send messages backwards in time, simply decide to measure enough chocolate until we spot enough hazelnut bars that the hazelnut hopper must be refilled earlier in the past when the chocolate was being made. Wonkers in the past now know that when the hopper is being refilled in a short space of time and that this is the signal from the future, and that future selves will take a two week break from Wonker chocolate and so no hopper will need filled for 2 weeks in the past. A signal passed backwards in time.
* For successful wonkerization, I only choose the chocolate fragments if they came from the machine at the same time. But this is fine, since the nut does not correlate to time, and the chocolate does not correlate to time, I haven't made any kind of school boy logic error.
Now I know you're skeptical. But my equation says its totally true. And I know I'm applying my Bells test after first filtering for the subset of chocolate bar fragments broken from the same bar, but I prefer to call these 'successful wonkerization of chocolate'. You don't understand, its all too complicated for you, what would a data mining scientist know about such statistical matters!
Warning, Wonkers Christmas Special Chocolate may contain nuts, and nut allegy people may die from the nuts, long after they've shit out wonkers out, when someone measures another entangled piece and that piece contains nuts.
If just there was a word for "Single Particle of Light"...
Rome taught me patience and assiduous application to detail. Virtues which temper the boldness of great, general views.
...hiroshima bombs as a unit of force...football fields as a unit of length...distance to the moon as a unit of wealth...
Still, not quite dumbed-down enough for me yet. What are these "photons" you keep mentioning? Or "computers"?
... but what's the message?
I can only determine one thing about it to the exclusion of all other things.
Can you do a followup with a goddam smoke signal?
Thanks.
It little behooves the best of us to comment on the rest of us.
Seems to be a breakthrough every week in quantum computing, but nothing is broken yet.
E Proelio Veritas.
How long is that in terms of football fields?
When all you have is a hammer, every problem starts to look like a thumb.
Well, why don't we really embrace the xmas spirit by hunting down and castrating OP. This is a news for nerds, not a pump-and-dump propaganda site.
Didn't they do this back in 04?
Get back to me when they achieve the same thing with a single wave.
Oh fuck you. :)
