"In usual materials it is very difficult to control nuclei directly," said Prof. Many quantum physicists have tried with little success. However, that also makes them extremely difficult to manipulate. Nuclei are promising contenders for quantum memory because they are not easily influenced by their surroundings. If the motion of the particles is disturbed, even a little, it throws off the whole calculation. While this is an extremely short time frame, only thousandths of a second, the particles involved are so small that they are easily influenced by their surroundings. To make quantum computing a reality, scientists must find a system that remains stable long enough to make the calculations. Quantum computing-which aims to use particles on the atomic scale to make calculations and store the results-has the potential to solve some key problems much faster than current computers.
