The day when you will have choice to opt for a home PC that will offer storage for trillions of bits of information per square inch may arrive within four or five years.
It’s not only a guess, but researchers at Imperial College and University College London are on their way to explore the possibilities of quantum computing in practicality.
They just found it possible with Metal Phthalocyanine (MPc), generally present in dye used for textiles and paper. A wide range of atoms like that of carbon, nitrogen and hydrogen at center were manipulated for atom’s magnetic moment. Dr Sandrine Heutz, of Imperial’s Department of Materials experimented with MPc clusters grown on plastic film to explore various ways to observe metal center interaction. Out of three states, the team could generate an on/off switch with copper and an on/entangled switch with manganese.
If they could successfully generate ‘Spintronics’ then an expanded system of binary calculation can be a reality that will reduce the area needed for bit of information to two molecules of 1nm3 in size. That means an obvious entry in quantum computing and height to processing power much greater than conventional computing. London Centre for Nanotechnology, a joint enterprise between Imperial and UCL, working on this project, is being funded by the Royal Society, Research UK and the EPSRC.
