Researchers from the National Institute of Standards and Technology (NIST) and the National Renewable Energy Laboratory (NREL) have reported a way to measure the amount of laser light needed to shift the electrons in a type of quantum dot between two discrete states—a low energy, ground state and a higher energy, excited state. Quantum dots may be able to serve as the ones and zeros in a quantum computer, once physicists have the ability to turn them "on" and "off". NIST's and NREL's new technique measures the dipole moment directly by enclosing the dots in a cavity, a dimming laser light pulse passing over them repeatedly. This in turn helps measure the dipole moment, indicating how easy the dots are to excite. For details, go to http://nist.gov.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
