Scientists take a quieter step closer to first practical quantum computer

Scientists working to produce the world's fastest, most powerful computers have moved a step closer to creating a practical prototype using microwaves – by shielding the atoms driving this new generation of computers from the harmful effects of noise.

Microwaves are already used in smart phone technology, but scientists are now looking at how they can harness microwaves so that atomic particles can be used to store and process data on a new type of computer called a quantum computer.

The ability to store and process huge amounts of data in a quantum way (on an atomic scale) would revolutionise computing, making it possible to carry out massive calculations and enabling computers to understand chemical reactions, create new medicines and carry out seemingly impossible simulations, such as the creation of our universe.
