DailyDirt: Diamonds, With Lucy, In The Sky
from the urls-we-dig-up dept
Carbon comes in several allotropes: graphene, diamond, nanotubes, buckyballs, nanofoam etc. Some forms are easier to manufacture than others, but someday we might have diamond-based semiconductors or diamond-based quantum computers. If you like shiny minerals, here are just a few interesting links on diamonds.- The world's first all-diamond ring -- no setting needed, but it's kinda difficult to re-size -- weighs in at about 150 carats and $68 million. And if it gets stuck on your finger, it'll be really hard to cut off without taking your finger with it.... [url]
- The 45-carat Hope Diamond could provide some insights on the geology of the Earth, but it's not easy to conduct science on famous museum artifacts. Scientists are looking at how boron makes blue diamonds blue, and they're etching off a few atomic layers of the diamond to determine how much boron is in it. [url]
- Diamonds can store qubits at room temperature for at least a couple seconds -- a pretty long time in the world of quantum physics. This discovery might lead to more practical quantum computers -- but general quantum computing is still a long way from becoming as useful as traditional computing. [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Qubits for seconds
Normal ram has to be 'refreshed' every 50 (give a or take a few dozen) milliseconds or it forgets its data--so a couple seconds would make it awesome RAM!

WOW,, how much does $68 Million weigh ?

Re: Re:
I also know, from a friend who does amateur jewelry work, that the moderate pressure of fitting a diamond into a setting can easily chip and crack it. Add that to the giant structure of the ring and all the places where pressure would be troublesome.. Just as well that it will probably never be worn.

So the qubits are not 'stored in a diamond' they are stored in Carbon 13 and nitrogen ions..
Consider a transistor in a plastic case, do you write that the transistor works because it is in a plastic case ?
"my computer works because the box it is housed in is metal !!"
Dont even bother to consider that "time" and qubits have a significantly different relationship to each other compared to 'normal' matter.
If something came be in two states (0 and 1) at any one time (superposition), then time itself ceases to be a significant factor. You simply cannot equate electronic computer concepts (like DRAM) to how a quantum computer could possibly operate.
You also might be able to store the state of a qubit over time, but you still need super cold equipment to read or write or 'program' information

Re:
it's all a part of the development of what hopefully will be increadable computing power, and work like that will or could make that possible sooner rather than later.
It's just that TD's take on it was flawed as usual..

Re: “carbon 13 (NOT DIAMOND)”
Let’s put it this way: if living things can’t tell the difference between carbon 12, carbon 13 and carbon 14, why should a piece of rock?

Re: Re: “carbon 13 (NOT DIAMOND)”
its position is irrelevent, it's still not diamond, even if it is IN a diamond.. is nitrogen 'diamond-y' as well ?

Re: Re: No. Not true. Also, silly.
When you slide a ring on, the skin of your finger can't move very much since it only goes from your fingertip down to the base. However when you try to pull the ring off, the skin can move quite a bit more, and ends up getting bunched up at the knuckle.
The solution for a stuck ring, in addition to using some kind of lubrication is to hold the skin taunt at the base of the finger while attempting to pull the ring off.

Re: Re: Re: No. Not true. Also, silly.
And on that note, please don't use your spit if you're going to hand the ring to someone else. That's just disgusting. Also, you can draw the skin taunt by slightly bending your finger.

Re: Re: No. Not true. Also, silly.
Not slip off or take off. Cut off. Specifically.
I used to manage a fine jewelry store, and we had to remove stuck rings on a regular basis. Most took a special little saw tool. Others, such as tungsten bands and this ring, require a C-clamp. Easy and relatively painless.
Been there, done that.
