Unleashing the power of quantum dot triplets

Quantum computers have yet to materialise. Yet, scientists are making progress in devising suitable means of making such computers faster. One such approach relies on quantum dots—a kind of artificial atom, easily controlled ...

Quantum leap in lasers brightens future for quantum computing

Dartmouth scientists and their colleagues have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, ...

Scientists produce a novel form of artificial graphene

A new breed of ultra thin super-material has the potential to cause a technological revolution. "Artificial graphene" should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher ...

Unusual material expands dramatically under pressure

If you squeeze a normal object in all directions, it shrinks in all directions. But a few strange materials will actually grow in one dimension when compressed. A team of chemists has now discovered a structure that takes ...

A new twist for quantum systems

Physicists at ETH Zurich have developed a method for precisely controlling quantum systems by exploiting a trick that helps cats to land on their feet and motorists to fit their cars into parking spots. In the longer run, ...
