What are current Physicists' general positions on the Copenhagen Interpretation?

In summary, there is no consensus among physicists about the validity of any quantum mechanics interpretation. However, there is a general acceptance of a Copenhagen-like operational interpretation for practical purposes. This interpretation has a "measurement problem" and there is ongoing discussion about its validity. The term "Copenhagen interpretation" has evolved over time and does not necessarily reflect the actual historical positions of Bohr and Heisenberg. Additionally, there are few attempts to connect their positions with modern developments in quantum mechanics. Overall, the majority opinion is to not worry too much about interpretations and focus on the practical applications of quantum mechanics.

TL;DR Summary
What is the general position of current physicist about the Copenhagen interpretation?
Actually, is not a doubt as a question, in which there is wrong or right. I just want to update myself with respect to the current physicists opinion about the Copenhagen interpretation of Bohr and Heisenberg. Summarizing, there is a consensus among the majority? In another words, there is still a discussion about the validity of this interpretation?

There is no consensus about any QM interpretation. None of them is generally accepted by physicists as the "correct" one.

There is still discussion about the validity of all QM interpretations.

The general view is to accept a Copenhagen-like operational interpretation of quantum mechanics as correct for all practical purposes. For example, the quantum mechanics textbooks of Landau and Lifshitz, Messiah, and Weinberg explicitly say that they use Copenhagen. The book "Operational Quantum Mechanics" by Paul Busch, Marian Grabowski and Pekka Lahti also states the operational viewpoint in its title.

At the same time, it is recognized by many that this orthodox interpretation has a "measurement problem" as it is gives special status to "measurements".

Yes, but you're not going to like it. The consensus is not to worry too much about interpretations.

Every month there are maybe 1000-1500 articles in Phys Rev. (A, B, C...etc) This month, the number of papers that could possibly fall into the category of "interpretations" is...<drum roll, please>...one.

Well... yes. In its minimalist operational form, it makes no claims about reality, so it carries no excess "baggage" like many other interpretations.

Note that when physicists use the term "Copenhagen interpretation" they are not necessarily talking about the actual historical position of Bohr or Heisenberg. The term has come to mean different loosely related ideas over time because there aren't any gold standard publications by the founders which rigorously define it. Also Bohr and Heisenberg haven't witnessed modern developments of QM (like decoherence). Attempts to connect the actual historical positions with modern QM aren't numerous (for an exception see Schlosshauer and Camilleri - The quantum-to-classical transition: Bohr’s doctrine of classical concepts, emergent classicality, and decoherence).
 

Related to What are current Physicists' general positions on the Copenhagen Interpretation?

1. What is the Copenhagen Interpretation in physics?

The Copenhagen Interpretation is a fundamental theory in quantum mechanics that explains the behavior of particles at the subatomic level. It was developed by Niels Bohr and Werner Heisenberg in the 1920s and is based on the principle of wave-particle duality, which states that particles can behave as both waves and particles.

2. How do physicists generally view the Copenhagen Interpretation?

The Copenhagen Interpretation is one of the most widely accepted interpretations of quantum mechanics among physicists. However, there is still ongoing debate and discussion about its validity and implications.

3. What are the main principles of the Copenhagen Interpretation?

The Copenhagen Interpretation is based on three main principles: the superposition principle, the uncertainty principle, and the collapse of the wave function. The superposition principle states that particles can exist in multiple states simultaneously, the uncertainty principle states that it is impossible to know both the position and momentum of a particle with absolute certainty, and the collapse of the wave function refers to the idea that a particle's state is only determined when it is observed.

4. Are there any alternative interpretations to the Copenhagen Interpretation?

Yes, there are several alternative interpretations to the Copenhagen Interpretation, including the Many-Worlds Interpretation, the Transactional Interpretation, and the Pilot-Wave Theory. These interpretations offer different explanations for the behavior of particles at the quantum level and are still a topic of ongoing research and discussion among physicists.

5. How does the Copenhagen Interpretation impact our understanding of the universe?

The Copenhagen Interpretation has had a significant impact on our understanding of the universe, particularly in the field of quantum mechanics. It has helped to explain and predict the behavior of particles at the subatomic level and has led to advancements in technology such as transistors and lasers. However, there are still many unanswered questions and debates surrounding the interpretation, and it is an area of ongoing research in the scientific community.
