Some very clever chappies in Australia have come up with a transistor that is seven atoms in size, which could lead the way to much smaller and more powerful computers.

Today's transistors and microchips will be considered bulky and cumbersome next to the next generation electronic wizardry being developed and at the forefront of this new technology are the researchers in the University of New South Wales in Australia bringing the dream of solid state quantum computers one step forward.

The seven atoms in a silicone crystal were replaced by hand with phosphorous ones using a scanning tunneling microscope and the working transistor was realised, but it is a long way away from production due to the fact that mechanized production will need to replace the handmade method used in creating the seven atom transistor.

This great achievement by Professor Michelle Simmons and his team, which will mean that smaller computers will not necessarily loose computational ability, and is part of work in progress to make a solid state quantum computer.

The prospect of components 100 times smaller than current ones really does mean that in the future the imagination will be the only thing that limits the notion of how small a computer will be.
