Announced the physicists are getting funding from the U.S. Department of Defense, they designed a system of "disappearance" time able to make the event a non-monitoring part of a second.
Inspired by the scientists of this device test of the research on the "robe of disappearances," the famous hyped Harry Potter, but instead to hide the particular purpose in a place, it is veiled from sight in time, what the study published in the journal "Nature," British.
He says Moti Friedman, research director of Cornell University in New York, who conducted this research, "The results that we have reached an important step towards the development of a robe a comprehensive time and place."
In order to design the device, based on scientists to the properties of the visible light spectrum, and that the different colors that posed by rapidly moving a little bit different.
Robe and starts disappearance "timeline" to issue a green beam of light in the cable made of optical fiber, and then pass this beam in the lens to divide Doin: blue light spreads more rapidly than the speed of the beam a little green and the original red light slightly slower.
Is increased and the difference in speed between the beams by placing a wall between them transparent.
At the end of the day, made up "time gap" between the red and blue beams, which reflect the optical fiber.
Although this gap is very small and only 50-Bekothanih, but it is enough to enter the shipment of the laser frequency is different from the frequency of light that reflects the optical fiber.
And after the introduction of laser shipment for a short time, under the red and blue beams of opposite who shall process a new checkpoint to speed up and slow down the red beam and then return the blue lens collection beams in the beam and one green.
The remaining shipment laser lasts for forty Bekothanih exist but they are not subject to monitoring, because it does not belong to a stream of photons on the green beam.
And Robert Boyd explains Shi Zemin and the University of Rochester in New York, that this process is similar to the intersection between the railway and the road to a crowded, when the train arrives, the car stop at the intersection, which occurs a "gap" in traffic.
Once the train passes even speed up the car which was parked in order to catch the other cars, and for the way of watching from a distance, looks perfectly normal traffic does not keep any evidence of the passage of the train on the intersection.
Shi and Boyd suggests that the goal is to reach the next researchers to increase the "time gap" that hide an event enough.
And considered that it can be enforced using the time to ensure the security of communications, because this process allows the division of traffic lights and make a different move quickly before re-collected. Thus, it becomes very difficult to penetrate the data.
The team gets Motti Friedman on the part of the funding agency of the Defense Advanced Research Projects of the Ministry of Defense, and on the development of future technologies close to science fiction might be used for military purposes.
This agency has developed in the late sixties a system to transfer data between computers, paving the way to the invention of the Internet.
