| Ultra-thin light detectors: Metamaterials and quantum cascade structures combined for first time Posted: 27 Mar 2014 07:06 AM PDT A new, extremely thin kind of light detectors has been developed. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures. Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light detectors.  |
| Posted: 27 Mar 2014 07:06 AM PDT Scienitists have 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.  |
| Computing with slime: Logical circuits built using living slime molds Posted: 27 Mar 2014 07:03 AM PDT A future computer might be a lot slimier than the solid silicon devices we have today. Researchers have revealed details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors.  |
