The orthodox quantum mechanics can describe results of observation but not an objective reality. Misunderstanding of its positivistic essence results to numerous mistaken publications, in particular about a possibility of a real quantum computer.
The contemporary controversy about the fundamental obscurity in quantum mechanics keeps on the old one about the aim of science, which was between the founders of the quantum theory. The orthodox quantum mechanics could be created only at the cost of renunciation of reality as the aim of natural science. The description only of phenomena, i.e. results of observation, should not be universal if no one believes that these phenomena are manifestation of a unique reality. Such belief concerning quantum mechanics is quite unacceptable because of irremediably conflict with special relativity. Nevertheless the quantum mechanics was developed and apprehended by most physicists as a universal theory of a quantum world. This fundamental discrepancy between the essence of the orthodox quantum mechanics and its history of development and studying has resulted both to an illusion about the aim of its description among most physicists and to the consideration of its fundamental obscurity as a universal problem among experts in quantum foundation. The aim of this paper is to show that quantum phenomena can not be described universally. It is indicated that rather the Schrodinger's than Born's interpretation of the wave function is valid for description of many quantum phenomena. The fundamental obscurity with which we are faced at the description, for example, macroscopic quantum phenomena differs fundamentally from the one with which the founders of the quantum theory were faced on atomic level.
We are currently in the middle of a second quantum revolution where the rules discovered a century ago to understand the quantum world are being applied to develop new quantum technologies [1]. Yet, most of the understanding of quantum physics is developed from the orthodox (also known as the Copenhagen) interpretation of the quantum phenomena [2], [3]. However, the orthodox theory has important difficulties in providing an intuitive view of quantum technologies because it states that a quantum object has only real properties when it is measured by an observer. This view of the reality of quantum objects is unnatural to engineers and, thus, is ignored by them when analyzing their realworld devices. What is natural to engineers is to imagine that the reality of an object (their properties) is independent of whether the object is measured or not.
Orthodox quantum mechanics, or at least some extreme interpretations of it, adopts a nonrealistic stance by assuming, in its fifth, or reduction postulate, that Reality is, in last instance, a making of the observer consciousness. The enormous empirical success of orthodox quantum mechanics lead most of the scientific community to accept without reserve this highly idealistic posture even without fully realizing its deep implications. Now, almost a century after its formulation, a return to a realistic view of Physics seems possible.
