Quantum Computers Using Microwave Technology
« on: April 03, 2013, 05:24:40 PM »
Scientist has got success in linking the quantum properties of two separated ions using microwaves to manipulate them. This is currently done with the help of laser beams and now this advancement can shrink the size of quantum computers. This research has been done at NIST (National Institute of Standards and Technology) which has been published in Nature. Microwaves have been used previously in manipulating single ions, but this is the first time when scientist from NIST used this on two separated ions places just 30 micrometers away. This kind of process give rise to a quantum mechanism which is crucial for information transportation and error correction in Quantum computers.


The mentioned experiment use desktop scale table of lasers and very small mirrors and lenses that are around 1/10 th of the sizes that are actually used these days. Microwave components can be easily expanded to make a practical quantum computer system. Also by using microwaves they were able to reduce errors that are however caused by using laser beams due to incorrect pointing issues and power.Scientist Dietrich Leibfried said that it may be possible to have a quantum computer of a size of smart phone in near future. More powerful quantum computer can be made up to a size of Desktop PC.
