Lasers can lengthen quantum bit memory by 1,000 times
ANN ARBOR, Mich.—Physicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers.
These precarious bits, formed in this case by arrays of semiconductor quantum dots containing a single extra electron, are easily perturbed by magnetic field fluctuations from the nuclei of the atoms creating the quantum dot. This perturbation causes the bits to essentially forget the piece of information they were tasked with storing.
A quantum dot is a semiconductor nanostructure that is one candidate for creating quantum bits.
The scientists, including the University of Michigan's Duncan Steel, used lasers to elicit a previously undiscovered natural feedback reaction that stabilizes the quantum dot's magnetic field, lengthening the stable existence of the quantum bit by several orders of magnitude, or more than 1,000 times.
The findings are published in the June 25 edition of Nature.

wow i didn't even think about that untill i read your second to last sentence. and then i had to think about it .....and then it hit me "Directer of Biophysics" and "optically driven quantum computers" and that is really freaking creepy.
I mean that basically means he's part of research for quantum computers for brains( or i suppose in any other spot of the body) right? Otherwise....what's the point of a biophysicist dealing with the development of quantum computers?
unless these are some kind of artificial brain concept designs....which is cool, but equally creepy...
