Clarification of the Nature of Quantum Theory Based on Scientific Philosophy

It is known that there was a disagreement between Bohr and Einstein about the nature of the fundamental equations of quantum mechanics. In 1949, in the work "Remarks on Articles," Einstein clearly expressed his thoughts on this issue. He wrote: "All this discussion was needed only to clarify the following. By attempting to defend the thesis that statistical quantum theory can in principle give a complete description of individual systems, we come to highly improbable theoretical concepts. On the other hand, the aforementioned interpretive difficulties of the theory disappear if quantum-theoretical descriptions are considered as descriptions of ensembles of systems"
