Baby Steps Toward Quantum Computers

Mz6 writes "In a step toward making ultra-powerful computers, scientists have transferred physical characteristics between atoms by using a phenomenon called entanglement, which Einstein derided as 'spooky action at a distance' before experiments showed it was real. Such 'quantum teleportation' of characteristics had been demonstrated before between beams of light. Teleportation between atoms could someday lie at the heart of powerful quantum computers, which are probably at least a decade away from development. Researchers using lab techniques can create a weird relationship between pairs of tiny particles. After that, the fate of one particle instantly affects the other; if one particle is made to take on a certain set of properties, the other immediately takes on identical or opposite properties, no matter how far away it is and without any apparent physical connection to the first particle." Reader starannihilator adds: "Physics Web provides a good graphic summary of the phenomenon, as well as a good technical article."

I am a quantum computer

...you insensitive clod!

Maybe Michael will make a smart thread one day.

Yet another example of Michael posting a story, trying to look like he knows something when he really doesnt. His intro would have been more accurate if he had just picked random words arranged into a paragraph.

The particles are not teleporting.

They are not communicating.

After entanglement, if you separate the particles and observe one of them, you then know the state of the other particle.

The fact that you know the state of one automatically determines for you the state of the other particle.

What makes it nifty is that until you make the observation, you can not know which particle is in which state.... schoedinger's cat. ... sylvester is both alive and dead until you look inside the box, but once you've looked, the outcome has been determined.
