In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these ...

Colloidal quantum dots are solution-based nanocrystals prized for their unique light-harvesting abilities. They can illuminate, create color, harness solar energy and function as semiconductors. These ...

However, the quantum states they rely on are prone to decohering – that is, losing their quantum information due to local noise. One possible way around this is to use quantum bits (qubits) ...

Using quantum states for processing information has the potential to swiftly address complex problems that are beyond the reach of classical computers. Over the past decades, tremendous progress has ...

A team of materials scientists from the University of Oklahoma has achieved what was widely considered impossible: successfully magnetizing quantum dots by "doping" them with manganese. Study: ...

One of the biggest hurdles in building quantum networks is showing that quantum information can be transferred between devices that are not inherently compatible. But one Europe-wide research ...
