Scientists create new recipe for single-atom transistors

Once unimaginable, transistors consisting only of several-atom clusters or even single atoms promise to become the building blocks of a new generation of computers with unparalleled memory and processing power. But to realize ...

Quantum phenomenon governs organic solar cells

Researchers at Linköping University have discovered a quantum phenomenon that influences the formation of free charges in organic solar cells. "If we can properly understand what's going on, we can increase the efficiency," ...

Which is the perfect quantum theory?

For some phenomena in quantum many-body physics, several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University ...

Superabsorbing ring could make light work of snaps

A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create 'superabsorbing' systems to make the 'ultimate camera pixel'.

Quantum entanglement only dependent upon area

Two researchers at UCL Computer Science and the University of Gdansk present a new method for determining the amount of entanglement – a quantum phenomenon connecting two remote partners, and crucial for quantum technology ...
