Physicists will reproduce the experiment with the Schrodinger cat

Physicists at the Institute for Quantum Optics and the Max Planck Institute of Photonic Sciences want to hold in reality, a famous thought experiment "Schrodinger cat." Quantum mechanics tells us that, as observed, each particle can only be in discrete states. But even in 1930 the Austrian physicist Erwin Schrödinger showed that prior to the measurement of the particle is in a superposition of possible states, and only at the time of observation "collapses" to one of nih.Doktor Oriol Romero-Isart (Oriol Romero-Isart) and his colleagues propose an experiment on "suspension" of tobacco mosaic virus (tobacco mosaic virus) in a superposition of two quantum states. His rod-shaped form (50 nanometers in diameter and 1 micrometer in length) most liked uchenym.Dlya beginning, they offered to put a virus in a vacuum, where he was caught in a trap created by the laser electromagnetic field. Then, another laser, the research team intends to slow down the virus, while it does not stop at one of the lowest energy sostoyaniy.Kak this happens, physics with photon force him to go to the superposition of two quantum states: prior to the measurement of the virus, in theory, should will be in a mixture of movement and stillness odnovremenno.Uzhe now some scientists dispute the scientific validity of the experiment. Thus, many of them believe that the virus can not be called a living organism. At that Romero-Isart answers: the same can be done with microscopic Tardigrada. Scientists know that they can survive in space vacuum for several days. Oh, they like something quite amiss in the role of "Schrodinger cat". There is another objection. "I am absolutely sure that the virus is comparable in size to microscopic inanimate object that will behave the same way as inorganic molecules," - said Professor Martin captive from Imperial College London. Nevertheless, he was curious to try a similar experiment, in fact, quantum mechanics implies that, theoretically, in a superposition of states may even be such a big object, like a car or chelovek.Koshka Schrödinger - hero seemingly paradoxical thought experiment of Erwin Schrödinger, whom he wanted to demonstrate incompleteness of quantum mechanics when going from subatomic systems to makroskopicheskim.V sealed box placed cat. In the box there is a mechanism containing a radioactive nucleus and a container of poisonous gas. Parameters of the experiment were chosen so that the probability that the core would collapse in 1 hour, is 50%. If the nucleus decays, it causes a mechanism in place, he opens a container of gas, and a cat gibnet.Soglasno quantum mechanics, if above the core shall not be monitoring his condition is described by a superposition (mixture) of two states - nondecomposed disintegrated nucleus and the nucleus, therefore, cat, sitting in a box, and alive and dead odnovremenno.Esli same box open, then the experimenter is obliged to see just any one particular state - the "core collapsed, the cat is dead" or "kernel is not split up, the cat is alive." The purpose of the experiment -- show that quantum mechanics is incomplete without some rules, which specify under what conditions there is a collapse of the wave function and the cat is either dead or still alive, but ceases to be a mixture of fact and drugogo.V many-worlds interpretation of quantum mechanics, which does not consider the measurement process than something special, both of cats there, but dekogeriruyut. When the observer opens the box, formed two state observer of the living and the dead cat, which (state) do not interact with drugom.Drugimi words, when the box is opened, the universe splits into two different universes, one of which the observer looks at the box with the dead cat, and in the other - the other observer looks at the living koshku.Originalnaya article describing the thought experiment published in the German magazine Naturwissenschaften ( «Natural Sciences) in 1935.
