Freezing single atoms to absolute zero with microwaves brings quantum technology closer

absolute zero

Physicists at the University of Sussex have found a way of using everyday technology found in kitchen microwaves and mobile telephones to bring quantum physics closer to helping solve enormous scientific problems that the most powerful of today’s supercomputers cannot even begin to embark upon.

Tiny grains of lithium dramatically improve performance of fusion plasma

While fusion might still be a far off dream, a new discovery may help bring that dream closer to reality. Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that could quicken the development of large scale fusion energy. The scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically.

A glass fiber that brings light to a standstill

Using atoms to slow light

Atoms coupled to a glass fiber: A system that can slow down light dramatically.

Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna University of Technology has now demonstrated that this problem can be solved – not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today.
