06 Jun 14. US Army develops new information teleportation network system prototype. US Army Research Laboratory (ARL) scientists have successfully demonstrated information teleportation using a new quantum-information processing technology. Developed over the last two years, the prototype information teleportation network system includes an information teleportation exfiltration testbed and approach, which securely moves quantum images when secure network communications are increasingly vulnerable to eavesdropping and hacking. The prototype was developed as part of the testbed to quantify the teleportation of information using eye-safe entangled photons, in a bid to demonstrate the potential for secure teleportation over optical fibre or through free-space. In entangled photon-based teleportation, a photon carrying potentially several bits of information interacts with an entangled pair of photons, enabling the data to be teleported to the other distant entangled photon and read by the recipient.
“This research will benefit future soldiers by helping provide the army with battlefield information teleportation networks that will be both cybersecure and fast.”
Army Research Laboratory quantum information principal investigator Ronald Meyers said: “The [Army Research Laboratory] teleportation achievements are expected to be the basis for new types of army mobile-information teleportation networks for battlefield enhanced situational awareness and security.
“This research will benefit future soldiers by helping provide the army with battlefield information teleportation networks that will be both cybersecure and fast. The success in achieving quantum teleportation over long distances through an obscured battlefield is difficult, but future mobile ad-hoc information teleportation networks can give the future army exponential advantages in cyber security, speed and bandwidth.”
In addition, the system is being developed for difficult military environments with turbulence and obscurants. (Source: army-technology.com)
11 Jun 14. DISA mulls laser system for satellite communications. To deal with growing communications problems such as an increasingly crowded electromagnetic spectrum and a growing risk of interception, the Defense Information Systems Agency will begin considering the use of laser-based satellite communications technology. Laser Light Communications announced a Cooperative Research and Development Agreement with the agency on June 10 in regards to the company’s Global Hybrid Satellite-Terrestrial All Optical Network Technology. The research effort will focus primarily on the potential use of an all-optical, laser-based, medium Earth orbit (MEO) communication satellite solution that could be seamlessly integrated into the global terrestrial communications network, according to the release. Laser communications would bypass the use of the traditional radio frequency spectrum by using pulses of light to communicate large amounts of information – the effect would be the same as using a fiber optic cable, but without an actual cable. NASA was the first to demonstrate the feasibility of laser communication in 2013. The Lunar Laser Communications Demonstration was able to transmit data from the moon to the Earth at a rate of 622 megabits/sec, which was six times faster than previous state-of-the-art radio systems. An all-optical satellite communications system is potentially capable of significantly increasing data transfer rates. Also, because the system doesn’t use the radio frequency spectrum, it won’t have to deal with spectrum allocation or mutual interference due to satellite spacing. The Defense Department currently is faced with increasing demand on the electromagnetic spectrum for military use while freeing up bandwidth for commercial use. (Source: Open Source Information Report
