Scientists from Aarhus University (Denmark) interviewed the colleagues physicists about their relation to popular interpretations of quantum mechanics, and also asked to answer the questions connected with the quantum theory.
Basic chaotic nature of the quantum phenomena, for example, disintegration of radioactive kernels, is recognized by 67 percent of respondents who believe that fundamental property of the nature is accident.
With statement that accident is feature of the physical theory and can’t be removed from it in any way, 18 percent of respondents agree. The fact that the randomness is only the seeming property of the nature, 12 percent of respondents consider, and four percent believe that there is a hidden determinism.
39 percent of respondents whereas 36 percent don’t give preference to any interpretation of the theory adhere to the Copenhagen interpretation of quantum mechanics. On six percent information and multiworld interpretations of quantum mechanics received.
The question “Whether You Consider What Physical Objects Have Well Certain before Measurement and Properties, Independent of It?” was negatively answered by 47 percent of respondents, and “positively, but in certain cases” — 27 percent. The fact that it always so, is considered by 11 percent. 15 percent of respondents found it difficult to answer.
The question “Where Exactly in Atom of Hydrogen There Is an Electron before Measurement?” of 49 percent of respondents was recognized by senseless, 26 percent considered what is everywhere, 15 percent answered that it can’t be known and 10 percent believe that it can’t be known at the current level of development of science.
Poll considers opinions of 149 physicists from eight universities of the world (originally authors distributed the list of questions to 1234 scientists, however most of them didn’t answer).
The nonrelativistic quantum mechanics describes behavior of the microscopic particles moving with speeds, much smaller velocity of light in vacuum. Now there are about ten interpretations of this theory.
Wave function with which evolution the description of observed systems is connected appears in the Copenhagen interpretation. In such approach to learn a condition of a quantum object (for example, an electron), the classical device is necessary (that is the device submitting to laws of classical physics). As a result of the procedure of measurement the electron changes a device condition, and on this change we judge an initial condition of a quantum particle. It turns out that it is possible to speak about the electron, having only performed over it measurement. The square of the module of wave function determines probability of a particle to accept this or that condition. It is possible to present it in the form of the amount composed (superpositions of conditions), and process of measurement comes down to extraction of one of possible composed.
