Quantum information isomorphism: Beyond the dilemma of the Scylla of ontology and the Charybdis of instrumentalism

چکیده
In order to deal most effectively with the unanalyzable quantum whole, the Copenhagen interpretation takes as a “frame of reference” the preparation parameters and outcomes of measurements. It represents a passive, Ptolemaic-like instrumentalism directly related to “what we see in the sky,” i.e., to the “surface” of reality. However, the notion of quantum information leads to an active, Copernican-like realism which involves an (intrinsic) ordering principle and the view that the quantum whole is analyzable. It is then possible to consider subsystems as localized in space, controlled individually, and communicated. This makes it natural to treat quantum information (quantum states) not merely as knowledge. Moreover, it involves complementarity between local and nonlocal information. To avoid the dilemma between the Scylla of ontology and the Charybdis of instrumentalism, we propose the concept of quantum information isomorphism, according to which the quantum description of nature is isomorphic to nature itself. By definition it is not just one-to-one mapping, but it preserves the full structure of nature. In particular, it allows the treatment of the wave function of isomorphic images of quantum systems in the laboratory, implying that quantum information is indeed carried by these quantum systems.

Diverse extrinsic and intrinsic cues must be integrated within a developing organism to ensure appropriate growth at the cellular and organismal level. In Drosophila, the insulin receptor/TOR/S6K signaling network plays a fundamental role in the control of metabolism and cell growth. Here we show that scylla and charybdis, two homologous genes identified as growth suppressors in an EP (enhancer...

در این پژوهش، خرچنگ‌های خانواده Portunidae در مناطق زیر جزر و مدی دریای عمان در استان سیستان و بلوچستان شناسایی شدند. نمونه‌برداری دو بار در طول سال‌های 89-1388و از 7 ایستگاه صورت گرفت.نمونه‌ها توسط تور ترال از 7 ایستگاه جمع‌آوری شده و در الکل 70% فیکس شده و جهت شناسایی به آزمایشگاه منتقل گردیدند. طی این بررسی در منطقه زیر جزر و مدی دریای عمان، مجموعاً 23 عدد خرچنگ جمع‌آوری و9 گونه متعلق به این ...
متن کاملPublic Transport Ontology for Passenger Information Retrieval
Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...

The effect of increasing quantum bits and Unruh effect on quantum Prisoners’ dilemma has been investigated for both entangled and unentangled initial states. The Nash equilibrium, as an important result of quantum game theory, was obtained through the different payoffs resulted from choosing various strategies. It has been shown that the non-inertial frame disturbs the symmetry of the game. Act...
