Rupert Goodwins' Diary
Blog So the world seems more interested in fluorescent pigs than entangled photons. I told those photons to get a better agent and sort out their image, but would they listen? Friday 13/1/2006 Look," I said.

Quantum Dots Lead To Entanglement Breakthrough
News Researchers at Cambridge University and Toshiba have announced a new quantum device that produces entangled photons. Consisting of pairs of photons whose fundamental properties are inextricably linked, this light has been attracting increasing...

Sony Reveals Blu-ray Pricing Structure
Talkback The technology concept is to use Polarized UV photons having resonant frequencies of the ferroelectric molecule along with Nano/Microwave Electric Fields to control electron movement, electron spin, electron electric field polarity, and electron...

Photon Mapping On Programmable Graphics Hardware
White Papers The implementation uses breadth-first photon tracing to distribute photons using the GPU. The photons are stored in a grid-based photon map that is constructed directly on the graphics hardware using one of two methods: the first method is a...

Toshiba Shows Practical Quantum Cryptography
News The system, which relies on single photons to transmit an untappable key over standard optical fibres, is capable of delivering thousands of keys a second and can be effective over distances of more than 100km.

Are These Wires The Future Of Crypto?
Blog In typical quantum crypto, the key to an encrypted message is sent from one person to another via a stream of photons of light. The NIST system shoots out photons at a wavelength compatible with existing fibre-optic telecoms networks.

'Noisy Light' Is New Key To Encryption
News If an eavesdropper disturbs the photons, then they're gone. What makes the system so secure is that an eavesdropper can't tap into it without disturbing the photons," said Paul Kwiat, a professor of physics at the University of Illinois at Urbana...

Rupert Goodwins' Diary
Blog Entangled photons are like Shakespearian lovers, of one soul but separated by cruel fate (in this case, Toshiba researchers). And so it may be with entangled photons. Tuesday 10/1/2006 One of my favourite treats is getting to write about weird...

Quantum Cryptography Becoming Mainstream
News Quantum encryption involves sending data by way of photons, the smallest unit of light. The photons are polarised, or oriented, in different directions. Magiq Technologies is creating a new line of products this year that it says could help make...

Researchers, Literally, Catch Some Rays
News The light, composed of particles called photons, essentially lost its zing as the information from the photons was transferred into the spin inherent in the gas atoms. Both MIT and Caltech are trying to build communication applications based on...

Future Fibre Networks To Exceed Light Speed?
News The scientists set up an experiment in which microwave photons — energetic packets of light — appeared to travel "instantaneously" between two prisms forming the halves of a cube placed a metre apart.

Intel Demonstrates Silicon Laser
News Photons generate far less heat than electrons do when used to carry data. The collision causes some of the photons to gain or lose energy, resulting in a secondary light of a different wavelength. When silicon atoms get struck by two photons at...

Intel 'peels Onion' With Nanosurgery
News Stick your chip in front of a camera and watch for those photons, and you can trace complex events as they percolate across your chip. You have to count individual photons over quite a long time, and do probabilistic analysis to screen out noise...

Are These Wires The Future Of Crypto?
Blog Comment I thought once you peeked at those pesky photons, all the secrets leaked out. This does get a bit confusing - how can the upconverter work while retaining the quantum magic that keeps the key distribution secure?
