    "abstract": "Karl Popper proposed a way to test whether a proposed relation of a\nquantum-mechanical state to perceived reality in the Copenhagen interpretation\n(CI) of quantum mechanics - namely that the state of a particle is merely an\nexpression of ``what is known\u0027\u0027 about the system - is in agreement with all\nexperimental facts. A conceptual flaw in Popper\u0027s proposal is identified and an\nimproved version of his experiment (called ``Extension step 1\u0027\u0027) - which fully\nserves its original purpose - is suggested. The main purpose of this paper is\nto suggest to perform this experiment. The results of this experiment predicted\nunder the alternative assumptions that the CI - together with the above\nconnection of the state function with reality - or the ``many-worlds\u0027\u0027\ninterpretation (MWI) is correct are shown to be identical. Only after a further\nmodification (called ``Extension step 2\u0027\u0027) - the use of an ion isolated from\nthe macroscopic environment as particle detector - the predictions using the\nrespective interpretations become qualitatively different.",
