The Measurement Problem Is a Feature, Not a Bug-Schematising the Observer and the Concept of an Open System on an...

Area of Science:

• Quantum Mechanics
• Philosophy of Science
• Foundations of Physics

Background:

• The informational approach to quantum mechanics interprets quantum theory through the lens of information and observer participation.
• Niels Bohr's philosophy emphasized the role of the observer and experimental context in quantum descriptions.

Purpose of the Study:

• To demonstrate the (neo-)Bohrian nature of the informational approach to quantum mechanics.
• To argue that this approach elevates observer schematization to a postulate, requiring a "Boolean frame" for measurement interpretation.

Main Methods:

• Philosophical analysis of the informational approach to quantum mechanics.
• Interpreting quantum mechanics as a "natural generalisation" of causal descriptions, incorporating observer schematization.
• Utilizing the concept of generalized open systems to address historical critiques.

Main Results:

• The informational approach inherently requires a "Boolean frame" (Boolean algebra) to interpret measurement outcomes and assign properties.
• The focus is shifted from metaphysical state vector interpretation to methodological property assignment within experimental contexts.
• A generalized concept of open systems can resolve Einstein's objections regarding spatially separated systems.

Conclusions:

• The informational approach to quantum mechanics aligns with Bohrian principles by postulating observer schematization.
• This framework provides a methodologically sound way to assign physical properties in quantum mechanics.
• It offers a resolution to long-standing debates concerning quantum mechanics and locality.
