Researchers open a new avenue to quantum computing with a breakthrough experiment: a large-scale quantum processor made entirely of light.
Read moreDouble layer of graphene helps to control spin currents
In order to make transistors that operate using the spin of electrons, rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be equal to the time taken for these electrons to travel through a circuit. Scientists have now taken an important step forward by creating a device that meets both of these requirements.
Read moreAlways on beat: Ultrashort flashes of light under optical control
Ultrashort laser pulses have enabled scientists and physicians to carry out high-precision material analyses and medical procedures. Physicists have now discovered a new method for adjusting the extremely short time intervals between laser flashes with exceptional speed and precision. The intervals can be increased or decreased as needed, all at the push of a button. Potential applications range from laser spectroscopy to microscopy and materials processing.

Researchers have developed a model that recovers valuable data lost from images and video that have been 'collapsed' into lower dimensions.
Read moreTiny particles lead to brighter clouds in the tropics
When clouds loft tropical air masses higher in the atmosphere, that air can carry up gases that form into tiny particles, starting a process that may end up brightening lower-level clouds, according to a new study. Clouds alter Earth's radiative balance, and ultimately climate, depending on how bright they are. The new paper describes a process that may occur over 40% of the Earth's surface.
