I belive that people typically underesitmate efforts required in materials science, this is not software or another chip design in well established CMOS process. It might easily take 20 years to make high volume, manufacturable spin based device. Severeal examples of new material developments that took 30-40 years do exist...Kris
After sucessfully developing a practical quantum entanglement technology, I wonder what will happen when like material is placed near the device. Will alpha/beta/gamma radiation affect atomic spin? Will radiation affect the ability to refresh data over time? Plastic or epoxy packaging can have a small radioactive component. These and other questions must be answered to achieve a working, reliable product.
quantum computers are still decades away, in my opinion, as simultaneous manipulation of group of atoms/electrons/photons is required. this article has good news about the long decay time of the information, which is very crucial for any kind of practical use.
NIST has been demonstrating how to store quantum information on atoms and last week Duke University and the University of Wisconsin showed how lasers could be focused with MEMS micro-mirrors to read and write them in their gaseous state: http://bit.ly/NextGenLog-h8ti
However, this University of Utah researcher takes the next step--holding out the promise of being able to store quantum information on solid-state atoms that can be read and written electrically, opening the door to quantum computers fabricated on chips just like conventional computers.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
