Scientists Are Bringing Back Vacuum Tubes for Computers of the Future

Submitted by: Odio @ 04:21 PM | Tuesday, November 8, 2016 | (url: http://www.popula...)

Researchers from UC San Diego are using vacuum tube technology to develop more efficient computer processors. The research could result in faster microelectronic devices and better solar panels. Their results are published in a paper in the journal Nature Communications.

Commonly thought of as a primitive precursor to the modern transistor, vacuum tubes were the building blocks of computers in the early 20th century, and computers built using them filled entire rooms or buildings.

The invention of the transistor in the mid 20th century allowed computers to be built much smaller, and paved the way for the computing revolution of the late 20th century. That being the case, the transistor is arguably the greatest invention in history.

google's quantum computer

seems cool, but we wont get one anytime soon. that shit has to operate at near absolute zero temps

Beyond the film, Google says it's made great leaps in recent experiments with the quantum chips, determining which algorithms work better in a quantum setup and providing further evidence that the D-Wave processor uses quantum entanglement, a behavior that links particles with no apparent physical connection between them. D-Wave has always claimed that its chips involved entanglement, but it had been difficult to conclusively demonstrate before now.

The first practical application has been on Google Glass, as engineers put the quantum chips to work on Glass's blink detector, helping it to better distinguish between intentional winks and involuntary blinks. For engineering reasons, the quantum processor can never be installed in Glass, but together with Google's conventional server centers, it can point the way to a better blink-detecting algorithm. That would allow the Glass processor to detect blinks with better accuracy and using significantly less power. If successful, it could be an important breakthrough for wink-triggered apps, which have struggled with the task so far.

HP's Memristor Changes Everything

Submitted by: DudeofDeath @ 10:48 AM | Wednesday, November 26, 2008 | (url: http://www.dailyt...)

"Memristors" are one of several memory technologies that have been theorized and promised in the coming years. HP has made a real memristor, however, and the way solid state memory is created and stored could have just changed forever. First theorized in 1971, memristors are basic circuits like resistors, capacitors, and inductors. These circuits are able to store data by allowing their levels of electrical resistance to fluctuate between high and low, or 0 and 1 to a computer. Like flash memory, they retain that data without power -- except they do it all on one circuit and at the speed of D-RAM.

IBM Brings Single-Atom Data Storage Closer to Reality

Submitted by: DudeofDeath @ 08:58 AM | Friday, August 31, 2007 | (url: http://www.physor...)

Such a storage capability would enable nearly 30,000 feature length movies, or the entire contents of YouTube, millions of videos estimated to be more than 1,000 trillion bits of data, to fit in a device the size of an iPod. Perhaps more importantly, the breakthrough could lead to new kinds of structures and devices that are so small they could be applied to entire new fields and disciplines beyond traditional computing.

IBM Creates Three-Dimensional Computer Chips

Submitted by: DudeofDeath @ 10:44 AM | Thursday, April 12, 2007 | (url: http://www.physor...)

IBM today announced a breakthrough chip-stacking technology in a manufacturing environment that paves the way for three-dimensional chips that will extend Moores Law beyond its expected limits. The technology called "through-silicon vias" -- allows different chip components to be packaged much closer together for faster, smaller, and lower-power systems.
