2010 March 30
It is an answer to the question raised by Erwin Schrödinger already in 1935 whether the quantum theory also remains valid in the classical world. Read more:

Today, on the 30th of March 2010, I read something scientific and want to bring here some excerpts:

Scientists put a micro mechanic oscillator into a non classic state of motion.

American scientists have cooled off a relative great resonator into its basic state. After that it showed a behaviour as it is otherwise only known of quantum objects.

The world of quanta is notorious for its strange laws. So an atom can be both excited and non excited and an electron both here and there. This has little importance for our daily routine. For in the macroscopic world there seems to exist no both and as-well-as. Here the one or the other rules, and in fact rigidly. Who thought so up to now must now open his eyes. American scientists have succeeded to put a micro mechanic oscillator into a state in which it both swings and does not swing.

Since several years scientists in the whole world put up a race to bring to light the hidden nature of quanta of swinging spring beams and other mechanical oscillators. A first aim exists in cooling them off so far that all thermal oscillations grind to a halt and the oscillator passes into its quantum mechanical basic state. In this state all motion with the exception of very fine trembling is frozen.

Quantum bits differ from ordinary bits in them not being able to just be in the states of zero or one, but also in a superimposition of these two. The scientists could also transfer such a state to the resonator - with the result that it swings and at the same time is in a state of rest.

For the first time a mechanical system was successfully put into a non classical state of motion.

This is a landmark which now allows steering classical mechanical systems with the same accuracy as individual electrons or atoms.

. . . speaks of a pioneering experiment. And he thinks that soon further breakthroughs will follow.

. . . an answer to the question raised by Erwin Schrödinger already in 1935 whether the quantum theory also remains valid in the classical world. Many scientists answer yes to this. They think that in principle every object can be brought into a quantum mechanical state of superimposition when one shields it enough from those influences which force a-one or the-other.
