New ‘switch’ could power quantum computing

140409134734 large

Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists have developed a new method for connecting particles — one that could help in the development of powerful quantum computing systems. The new technique allows researchers to couple a lone atom of rubidium, a metal, with a single photon, or light particle. Continue reading “New ‘switch’ could power quantum computing” »

Orbital computing: An atomic-level tech for future computers

LightSwitch

There seems to be no end to the claims that the data storage technology of the future has just been found.  But that hasn’t stopped one researcher from suggesting that his new discoveries could lead to read-write speeds several thousand times faster than anything now imagined for fancy magnetics or spintronics.

Switching with single photons: this is a step towards the quantum computer

foton switch

The idea to perform data processing with light, without relying on any electronic components, has been around for quite some time. In fact, necessary components such as optical transistors are available. However, up to now they have not gained a lot of attention from computer companies.

A single-atom engine breaks the laws of physics and progress in quantum computing

atomic engine

A new invention from Germany’s University of Mainz is not only the world’s smallest engine by an enormous margin, it may have broken a theoretical limit for engine efficiency. The device, a so-called “atomic engine,” produces power thanks to the movements of just a single atom trapped and manipulated. It’s an incredible achievement that, while not particularly useful for engineering in the short term, could revolutionize our understanding of the quantum world. Plus, it’s really neat.
