An invisibility cloak bends time to hide encrypted data sent over fiber optic cables.
As previously reported by The Inquisitr, the invisibility cloak is a continual object of fascination.
Current attempts at perfect Harry Potter invisibility cloaks have produced an invisibility cloak that would be good as camouflage when viewed from a distance. Some scientists believe it’s only a matter of time before invisibility cloaks can be produced by 3D printers at home, giving every Harry Potter fan hope their dreams may be fulfilled.
This new type of invisibility cloak, or time cloak, is not what we’re used to thinking of as an invisibility cloak because it’s hiding information over a fiber optic cable, not the visual wavelengths most people want. But it’s not like this makes this invisibility cloak less important. This technology has the potential of creating ultra-secure communications systems that no one can break. With the US government’s NSA starting to monitor the internet traffic of American citizens, and the Verizon user data scandal, many Americans might desire this so-called invisibility cloak become available for the average joe.
This invisibility cloak works by manipulating light wavelengths to cancel each other out and create a “gap” in time where information can be hidden where light does not exist. The researchers say, “It doesn’t just prevent eavesdroppers from reading your data — they wouldn’t even know there was any data there to hack.
But so far this invisibility cloak for data only works 46 percent of the time and the recipient cannot even tell it’s coming. The good news is they are able to slip in 12.7 gigabits of data per second.
The researchers explain how their invisibility cloak hides the data in time:
“If you consider light as a flow of particles a bit like cars going down a highway, you can imagine that some of the cars at the front of the stream speed up and ones behind slow down so a gap can open up. … By doing this type of interference effect, we focus the light to even smaller points in time. So, in the middle, we have all of our energy focused on very small points, and between them, we have regions where, if something were to happen, it would not be detected because there’s no light there to pick it up.”
Do you think this invisibility cloak for data should be made publicly available?
