Copenhagen Interpretation and collapse moment

In summary, the Copenhagen Interpretation states that according to the standard theory of QM, a measurement apparatus can be in a superposition of possible outcomes. However, it does not provide an explanation of how a single decisive outcome is obtained. The Many-Worlds Interpretation, on the other hand, assumes that the measurement apparatus is never in a superposition of states and that a single measurement result is obtained when the Born rule is applied during a measurement. While the CI does not provide an explanation for how a single outcome is obtained, it does specify that it occurs when a measurement is performed.

Is it still true that under the Copenhagen Interpretation the standard theory of QM tells us that a measurement apparatus gets into superposition of possible measurement outcomes and does not tell us how and when we get a single decisive outcome? (The so-called "Measurement problem")

This is what the MWI says. The CI assumes the measurement apparatus is never in a superposition of states. It says you get a single measurement result when you apply the Born rule(and do a measurement).

It doesn't tell how, but it does tell when. It's when a measurement is performed. Now if you wonder how then the time of decay is random, see my https://arxiv.org/abs/2010.07575 .

FAQ: Copenhagen Interpretation and collapse moment

What is the Copenhagen Interpretation?

The Copenhagen Interpretation is a popular interpretation of quantum mechanics, developed by Niels Bohr and Werner Heisenberg in the 1920s. It states that the act of observation or measurement of a quantum system causes it to collapse into a definite state, and that the observer plays a crucial role in determining the outcome of an experiment.

What is the collapse moment?

The collapse moment, also known as the collapse of the wave function, refers to the moment when a quantum system transitions from a state of superposition (existing in multiple states simultaneously) to a definite state. This occurs when the system is observed or measured by an external observer.

Is the Copenhagen Interpretation widely accepted?

Yes, the Copenhagen Interpretation is one of the most widely accepted interpretations of quantum mechanics. However, it has also been heavily debated and criticized by other interpretations, such as the Many-Worlds Interpretation and the Transactional Interpretation.

Does the collapse moment have any real-world implications?

The collapse moment is a fundamental concept in quantum mechanics and has been experimentally verified. It has also been applied in various technologies, such as quantum computing and cryptography. However, there is still ongoing research and debate about the exact nature and implications of the collapse moment.

Can the collapse moment be observed or measured?

No, the collapse moment itself cannot be observed or measured. It is a theoretical concept that explains the behavior of quantum systems. However, the effects of the collapse moment can be observed through experiments and measurements of quantum systems.
