Scientists create quantum state that is visible with microscope

Physicists have managed to observe quantum mechanical effects in an object that can be seen through a standard microscope. This is the first time researchers have been able to see a large object in two places at once, until now this "quantum state" has only been accomplished with single particles, atoms and small molecules.
In this experiment, published in the journal Nature, scientists produced a quantum state in an object billions of times larger than previous tests. The team says the result could have significant implications in quantum computing.

"There is this question of where the dividing line is between the quantum world and the classical world we know," said Andrew Cleland of the University of California, Santa Barbara.
"We know perfectly well that things are not in two places at the same time in our everyday experience, but this fundamental theory of physics says that they can be," he told BBC News.
Now, Professor Cleland and his team have moved that dividing line, using an object just big enough to be seen with the naked eye.
