A team led by the University of Colorado Boulder is pioneering a new solution to the problem of spring cleaning on the moon: Why not zap away the grime using a beam of electrons? The research, published recently in the journal Acta Astronautica, marks the ...

New theory hints at more efficient way to develop quantum algorithms

In 2019, Google claimed it was the first to demonstrate a quantum computer performing a calculation beyond the abilities of today's most powerful supercomputers. But most of the time, creating a quantum algorithm that stands a chance at beating a classical ...

Researchers develop molecule to store solar energy

Researchers at Linköping University, Sweden, have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption.
