The future of electronics is light

As electronic transistors get tinier, they approach a point at which they won't be able to get smaller. How can we keep shrinking our devices, and making them more powerful at the same time? Light.

Hold it right there: how (and why) to stop light in its tracks

Freezing light in mid-air isn't just the realm of Star Wars, as new research shows. But what do you do with the light once it's trapped? One option is to use it to develop new forms of computers.
Teleportation is still well and truly entrenched in science fiction, unless you’re a photon. Photon™

Teleportation just got easier – but not for you, unfortunately

Thanks to two studies published in Nature last Thursday, the chance of successful teleportation has considerably increased. Which is a good thing, right? Whether or not you’ve ever been on a long-haul…
When you shine a torch into a dusty room, not all the photons reach their destination. Simon Greig (xrrr)

‘Louder’ light could power a brighter quantum future

All of the light we see around us comes in chunks of energy known as photons. As well as making up light, photons can be used to carry and process information and their quantum properties make possible…
