Theoretical physicists Noah Linden and Sandu Popescu, along with graduate student Paul Skrzypczyk, all of the University of Bristol in England, describe their concept in a paper to be published in Physical Review Letters. If it can be implemented, the work could find use in preparing qubits, which are often single atoms, for use in quantum-information systems by initializing them to a known state.

The other day we could see how physicists managed to read entangled photons at an unprecedented distance of 16km. Today we can read that physicists in Bristol can set particles to a known state.

It's awesome! Awesome I tell you.

The quantum is yielding its weird secrets. :)

The highest physics course I took was still just a 100 level in undergrad, and that was quite a while ago. Should I take your word for it, or do you want to translate the article?

The role of a theoretical physicist is to use known mathematics and tested physics to create models to explain phenomenon and to create models for experimental physicists to try and see if they hash out. In the article, they state that they created a model that could be tested out to be verified by the experimental physicists.

Unfortunately the way things (energy, food, water, climate) are going right now, we don't have time for theoretical anything. We need Proof of Concept, and production scale ASAP.

The problem with that is that without the theory, we can't be expected to experiment and find the phenomena we're trying to look for.

I'm fully aware of that--it was kind of the point. We're about out of time.

(Assuming time is linear ... a whole other conversation)

The world is going to collapse tomorrow. Didn't you get the memo?
OMG!!! They lied all along! I was SURE I would have until 2012!
Space, time, it's all an illusion anyway.
Yeah, I wanna hear you say that after you get sucked into a black hole.

And hovering just Beyond The Blue Event Horizon doesn't count.
