Quantum computer closer to development
Government physicists say they`ve used charged atoms to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds.
National Institute of Standards and Technology scientists say their latest quantum version of computer memory lasted more than 100,000 times that of previous experiments on the same ions.
They said the progress improves prospects for making practical, reliable quantum computers that will make use of the properties of quantum systems rather than transistors for performing calculations or storing information.
Quantum computers, if they can be built, could break today`s best encryption systems, accelerate database searching, develop novel products such as fraud-proof digital signatures or simulate complex biological systems to help design new drugs.
The research is described in the Aug. 5 issue of Physical Review Letters.
