I wonder if this will impact the security of quantum encryption?

Yes Heisenberg, not Hindenberg which went all splody on us.

Yeah, Science Mr. White! Science, B!TCH!

There used to be a desktop image, I think it came standard on Windows ME, that depicted atoms or molecules and their curving and arcing trajectories.
it was neat.

Can you accurately predict how much you affect the momentum or position by attempting to measure both?
A photon has a known energy and its effect can be subtracted out. So if a particle slows down, you know how fast it might have been if you hadn't tried to measure it.
Then there is schroedinger’s cat and its relationship?

Suddenly I have gone all wobbly.

Eugene Polzik of the University of Copenhagen in Denmark is impressed: ‘It sets a new and clever way of measuring certain magnetic field disturbances using an ensemble of quantum spins,’ he says. ‘It would be easy for me to look at this and say “Oh, yes, right: it doesn’t contradict quantum mechanics,” but to figure out how to achieve this, to understand how relevant it is and under what circumstances it is relevant – this is an excellent and elegant development.’
...
At least from this part of the article, which was saved for last, the uncertainty principle is still intact.

Avoid the entanglement, eh?

Next step, transporters.

0bama is like a black hole spinning. There is not anything that will slow down his spin.

Speaking of uncertainty, Get back to me after you have divided the spin radius by two and reached zero.
I won’t be waiting...
