Stoping light in quantum leap

Perhaps not 'stoping' so much as slowing it down. Again, I am amazed. Who would've thought you can slow light down?

Naturally, it's not that simple. Nothing is simple, or common sense, in the quantum world. It seems they use a vocabulary that's similar to our normal day-to-day language (be that english or south eastern mongolian, I suspect), but differs from it in crucial aspects. Differs just enough to be most confusing. It helps to remember that when the word 'quantum' is used in a scientific report, then the meanings of all other words in the report (including 'the' and 'a', or 'stop' for that matter) should be interpreted with that in mind. The meanings of these words also seem to enter the non-intuitive realm of quantum mechanics. Okay, I won't get any more lyrical on the subject. You get the idea.

The article relates to quantum computing, rather than to slowing down light. The techniques used here will pave the way, theoretically, to quantum computer memory. From what I understand, this is a very big step towards the reality of quantum computers.

Researchers from the Laser Physics Centre in the Research School of Physical Sciences and Engineering used a modified crystal to ‘stop’ light for over a second, more than 1000 times longer than earlier attempts.

“Stopping light is not just a neat trick, it is the basis of a quantum memory — a device capable of storing and recalling the quantum states of light. This is one of many quantum computing components under development in our lab,” Dr Sellars said.

“We have gone out on a limb pursuing our unique approach to quantum computing. What our new record shows is that we are on the right track,” Dr Longdell said. “Now, if we can store a single photon we will have demonstrated the world’s first quantum memory.”

I'll keep an eye on this thread...and then perhaps I can add it to the 'quantum computer timeline' in the wikipedia
