A research team in China has built a quantum dot device that produces photon pairs with record-setting purity, achieving a two-photon fraction of 0.983(1). The work, published in Nature Materials, ...

Attosecond pulses enable sub-femtosecond studies of ultrafast electron dynamics. Since 2001, pulse durations have shortened ...

Introduction:Attosecond pulses capture ultrafast electron and light–matter dynamics on the shortest timescales accessible to controlled experiments ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

Solar water splitting is one of the most direct ways to produce green hydrogen using sunlight. However, most photocatalysts ...
