Usual transistors will be converted to quantum transistors [Archive]

Well, I know this can be old news, but I read it a few days ago and I think that it can be interesting.
The nowadays transistors are getting smaller and smaller in size, but we are next to its limit of miniaturization, to replace it, they are going to use the spin of the electron, being faster than nowadays transistors and producing less heat.

If you remember it, the electron can have two spins, spin up and spin down (that can be +1/2 or -1/2), those spins can be identified as binary "0" and "1". This spintronic technology would be able to control that.

Also literally:
Low-power spintronic chips and transistors will combine logic and memory -- presently separate functions, Andy Sachrajda said. "Currently, logic is usually carried out using conventional electronics, while spin is used for memory," he explained. "Spintronics will combine both functions."

Amazing, isn´t it?

Yep, there are so many fundamental changes coming up in the next 10-20 years for computers that they will no longer be recognizable by the time my kids are even in high school!

These changes include:

MRAM: Super fast, cheap, dense and non-volatile memory to replace hard drives and the boot cycle. It will combine storage and RAM into one seamless thing.

OLED Displays: Organic Light Emitting Diodes. Will replace flat panels by being flatter, brighter, and cheaper, use less power and have higher resolutions.

Spintronics: (Listed Above)

Nanotechnology: Will continue to find its way into computers bit by bit (pun intended) in the coming years, enhancing all aspects of computers.

Asynchronous chips: The clock speed will no longer hold back a chip by its slowest part, but allow each part to function at its fastest possible and eliminate timing problems.

Brain-Chip interfaces: Coming sooner then you think, will allow users to connect to a computer and have a direct mental experience with it. No more displays, speakers or input devices, all you have to do is think and the mouse pointer moves, the image and sound are pumped directly into your brain and is visualized there, by-passing the senses!

Holographic data storage: After Blu-Ray and HD-DVD are forgotten, storing data in 3D will be common place. This allows for using the 3rd dimension to store data and boost storage to 100+ terabyte, cubic centi-meter sized cubes of yellow polymer resin, read by 2 laser beams and accessed in pico-seconds at multi-gigabyte per second transfer rates. All the DVD movies in the world will be storable on just a handful of these cubes!

Quantum Computers: Using quantum properties of sub-atomic particles to process data will allow a current day super computer to lie in the palm of your hand, and have a 100 day battery life.

Photonic Crystals: Using photons, particles of light, to take the place of current-day electrons in circuits will allow for seamless optical processing, storage, and transfer of data at much lower power consumptions and much faster rates of course.

In 50 years...

Wireless, implanted computers, using the best of the above technologies and others yet imagined, connected directly to your brain and linked to everyone else's brain chip in the "mental-net", will allow the rise of the Borg to take place. All experiences and control interfaces are done through the imagination with no hardware on the user other then the chip implant. Your eyes and ears will be web-cams and microphones. Your body will respond to the will of the master computer, and all your thoughts will be recorded. You would be "dreaming" your game in full realism! Resistance is futile! :twisted:

The above seems less far fetched every day...
