Quantum contextuality denotes the principle that the measurement outcomes of certain physical quantities depend on the context, implying that the properties of a quantum system cannot be predefined independently of other measurements. This challenges classical assumptions of objectivity, suggesting that quantum mechanics inherently resists a simple realistic interpretation where physical properties exist prior to measurement.

measurement outcomes

Physical quantities are properties or phenomena that can be measured in the physical universe, expressed as a combination of a numerical value and a unit of measurement. They are fundamental to the study of physics, enabling the description, analysis, and prediction of natural phenomena through mathematical relationships and laws.

classical assumptions

Objectivity refers to the practice of maintaining impartiality and neutrality in analysis, judgment, and reporting, free from personal biases, emotions, or external influences. It is crucial for ensuring credibility and reliability in fields like journalism, science, and law, where unbiased information is essential for informed decision-making.

objectivity

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

realistic interpretation

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity. These properties are crucial for identifying, classifying, and using materials in various scientific and industrial applications.
