Quantum state created in largest object yet

SpuriousLogic (1183411) writes "Researchers have created a "quantum state" in the largest object yet.
Such states, in which an object is effectively in two places at once, have until now only been accomplished with single particles, atoms and 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.
Now, Professor Cleland and his team have moved that dividing line, using an object just big enough to be seen with the naked eye.
They used a tiny piece of what is known as a piezoelectric material, which expands and contracts when an electrical current is run through it.
The result is a huge push toward answering the question of whether quantum mechanical effects simply disappear in objects beyond a certain size.
"As far as mechanical objects are concerned, the dividing line was at around 60 atoms," Professor Cleland said.
"With this experiment, we've shown that the dividing line can be pushed up all the way to about a trillion atoms.""
