When you look at your particle and collapse it, I don't suppose it is possible to tell if you collapsed it someone at the other end did? Because if you could, you could have a whole bunch of them, look at them at a predetermined time, and then the information would be contained in which particles were already collapsed, not what state they were now in.
But I suspect that, in fact, you cannot tell if the collapse was caused at your end or the other.
Put another way, can you tell when the state changes?
For some reason, this reminds me of the problem of transfering encryption keys over an insecure network. Maybe there is a public-private key analog for quantum communication?;) A long shot.
This wiki looks good, and if it isn't too technical, maybe I can find the answer. However, every other article, paper, or discussion that I have seen skips this one question of mine: How is the choice made between all the superimpositions to select ther 'right' answer? Everyone goes to great lengths to explain the superimposition part and its implications for massively parallel computation, but no one ever says how you choose the result! Does anyone have a clue about this?
E&OE doesn't have anything to do with whether they have to sell at an advertised price or not. It's merely a statement limiting their liability in general : Equity and Owner's Equity. You'll have to ask a lawyer or an accountant for a better explanation.
Didn't anyone else choose sets based on the pieces they contained? I use to spend weeks analysing the pictures on the boxes and in the pamphlets, trying to figure out exactly what pieces a particular set contained.
My friends and I eventually pooled our sets for greater variety. The core was an old (first space line?) spaceship, about two and a half feet long, all transpearant-blue and opaque-white pieces. It broke into two small fighter ships, a chasis, and a lab. Anyone remember that one?
All that stuff in there about their corporate culture sounds nice, and I'm sure they love kids, but compare the prices in the article: $79 for the 600+ piece Dino set and $19 for the 1,200 piece bucket of bricks.
Don't get me wrong, I love legos (yes, I use an 's'). In fact, I can't imagine my childhood without them.
I'm not sure what it is at now, but a few years ago titanium was around 32 dollars a pound. Good bicycle frames weigh less than 4 pounds. However, titanium frames start at 800 dollars and go up, way up. So I'm thinking most of the cost is in the manufacturing. Still, every bit helps, eh?

"... the ability to seamlessly integrate other distributed computing projects ..."
So they say, but what do they know about this?
I thought that once you observe it, from either side, the entanglement disappears. Is this correct?
