Diamonds heated In Microwave Oven will Protect Your On-line Purchases!
Encrypted messages used for credit card purchases online, may be become even more secure thanks to diamonds heated in a glorified microwave oven.
The new technology is by James Rabeau, a research fellow in the University of Melbourne’s School of Physics.
How does this innovation work? Most high speed communication networks use light particles, or photons, to transfer information. Trillions of photons speed down optical fibres all over the world, transferring all manner of sensitive details.
This is where 'quantum cryptography,' which involves using single light particles to encode information, comes in. The concept of quantum cryptography has been around since the 1980s, says Rabeau, but no one so far found a way of producing single particles of light reliably and efficiently at room temperature.
Rabeau has built a device that would deliver single photons from diamonds into an optical fibre. The new technology that Rabeau has patented is based upon a process known as chemical vapor deposition (CVD,) which takes place in a glorified microwave oven, to deposit diamond crystals at one end of an optical fibre. When a laser hits the diamond encrusted tip of the optical fibre, single photons are wrapped around the data and sent down the optical fibre as part of a message.
Rabeau has a worldwide patent on the process, which provides the first reliable and cheap source of single photons.
James, when you're done with this, see if you can get computer screens developed with robotic arms that will deliver diamonds and jewelry. WOW! Wouldn't that be something!

Between me and my husband we've owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I've settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.

I think Aol. Really should be each the most effective as well as the worst of the yr. It is the ideal, because yes, it will be observed by far the most. It also does set a long term for the model, incredibly diverse from their past as Web, Inc. It really is also fairly imaginative; it is very unique. It will need to be the worst though since the execution is horrible. The idea, nevertheless is creative, just sucks. There may be very little cons istency, as well as the wordmark bores me.
