Diamonds Are a Quantum Scientist's Best Friends

An international group of scientists led by researchers from the University of California in Santa Barbar have taken the first steps toward creating a quantum computer -- in a diamond. So far they've built a two-qubit unit for a quantum computer. A qubit is the quantum computing equivalent of a bit, and it can be both on and off at the same time, unlike a regular bit which must be in one state or the other. The electron spin precesses extremely fast in a magnetic field, while the nuclear spin is about 1,000 times slower.

MIT's Smart Sand Can 'Build' Whatever It Touches

Of late, people working in specialized fields such as industrial design, architecture and the medical and dental industries have been going gaga over 3D printing, a process in which three-dimensional solid objects are produced on a special printer using materials such as molten polymers. However, this technology may be trumped by research on so-called self-sculpting sand being conducted at the Massachusetts Institute of Technology. The material's not really sand. Instead, it's what you might want to consider pebbles -- cubes measuring 10 mm to a side.

Tapose Is a Good Idea Gone Bad

Tapose is a great idea for a tablet app that was pushed out the door too soon. After four months in the Apple review process, the journal software arrived at the App Store recently, but it still doesn't seem ready for prime time. On a first-generation iPad, it's often unresponsive, buggy and prone to frequent crashes. It's not very intuitive, either. That's a sad state of affairs, because the app, which turns the iPad into a multi-purpose journal, is a based on a terrific concept.

Smart Diagram Effortlessly Produces Professional-Looking Results

The much talked about demise of the laptop in favor of tablet device, it could be argued, will be dependent on the tablet offering much of the functionality of the laptop. Gaping holes in tablet function will likely perpetuate the laptop as a tool. A number of work-type Android applications have successfully migrated to the tablet form: Microsoft Office-like apps; printer-sharing apps; document-scanning apps. Well, here's a test. What about Vizio-like diagramming? Smart Diagram Pro from Sillycube, offered for $4.30 on Google Play, is the full version of a stripped-down Smart Diagram app that lets you create diagrams on your phone and tablet.
