Waves polarized material

Waves polarized material

In the case of the experiment performed at the Institute Laue-Langevin, photons are replaced by polarized neutrons (their momentum clean, the spin is oriented in a definite direction in space), which thus behave in part like waves like photons. Those with a parallel spin their movement and oriented in the same direction borrow the way up on the previous scheme. While those whose spin is antiparallel follow the way down. One can use a magnetic field able to interact with the magnetic moment of the neutron. This stems from the fact that, although no overall charge as the electron , the neutron behaves as a magnetized rotor (can be convinced, for example, considering that it contains electric currents because it consists of quarks loaded in motion).

Typically, a highly disturbing a quantum measurement object, detecting a photon often returns to absorb for example. However, as shown by Yakir Aharonov and others, it is possible to make measurements slightly disturbing some quantum systems. In the experience of Grenoble, it is shown by this method that everything happens as if a single neutron had traveled by road from the top while its magnetic moment , so its spin was measured "low" using a magnetic field in the path of the bottom. Seen with interference fringes that can occur with neutron beams. The particle seems to behave indeed like a cat quantum Cheshire since its spin is found measured in a place where it should not exist.

According to researchers, this strange phenomenon is expected to have applications in the fields of metrology precision and technology of quantum information.
