Ozawa's Intersubjectivity Theorem as justification of RQM's postulate on internally consistent descriptions
arXiv:2401.06185 · doi:10.1007/s10701-024-00762-w
Abstract
The Ozawa's Intersubjectivity Theorem (OIT) proved within quantum measurement theory supports the new postulate of relational quantum mechanics (RQM), the postulate on internally consistent descriptions. We remark that this postulate was proposed only recently to resolve the problem of intersubjectivity of information in RQM. In contrast to RQM for which OIT is a supporting theoretical statement, QBism is challenged by OIT.
