Quantum dots provide complete control of photons

By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.

These photons are running out of loopholes

A team of scientists led by Austrian physicist Anton Zeilinger has conducted a potentially groundbreaking experiment with photons by closing an important loophole.

This 'bulk' silicon emits visible light

Electronic computing speeds are currently hovering around raw limits imposed by the laws of physics.

Laser system can see round corners

A new laser system captures the behavior of individual photons and uses advanced optics to deduce what's around the corner.

Photons teleported over 60 miles

Chinese scientists have smashed the distance record for quantum teleportation, zapping entangled photons over 60 miles.

Trillon fps camera fast enough to film photons

MIT's created a camera that can capture a trillion frames a second - the ultimate in slow motion, say its developers.

Time travel proved impossible, physicists claim

A group of physicists at the Hong Kong University of Science and Technology (HKUST) say they've proved that single photons cannot travel faster than the speed of light in vacuum, effectively putting the kibosh on the idea of time travel.

Physicists create new type of light

Physicists from the University of Bonn have developed a completely new source of light, previously thought to be impossible - a so-called Bose-Einstein condensate consisting of photons.
