1. Answer Review by Eric Plat

Entanglement is a feature of the mathematics involved in quantum theory.
Correlations observed in physics are part of the elementary particles created as the result of chemical reactions. This has nothing to do with mathematics,
Experiments match up with the predictions made by it.
Tricky. First you have experiments. Secondly are the explanations of these experiments i.e. the details of the reaction observed.
An entangled state is one where it only makes sense to describe the properties of several things together instead as a state for each of them.
More detail is required.
What does entanglement imply for reality is up to interpretation. There are many different opinions on what is going on “under the hood”. Since we don’t have any experiments that distinguish between different interpretations of quantum mechanics most physicists don’t put much weight into it. It is the way it is.
Each different reaction requires its own explanation.

Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become connected in such a way that the state of one particle is dependent on the state of another, regardless of the distance between them. Physicists have developed various interpretations and theories to explain quantum entanglement, but there is no universally accepted explanation. Some of the key interpretations and theories include:
  • Standard Quantum Mechanics: In the framework of standard quantum mechanics, entanglement is a fundamental feature of the theory. When two particles become entangled, their states are described by a joint quantum state that cannot be decomposed into individual states for each particle. The evolution of the entangled system is governed by the principles of quantum mechanics, including superposition and non-locality.
  • Quantum Field Theory: In the context of quantum field theory, entanglement can be understood as correlations between degrees of freedom of a quantum field. This perspective treats entanglement as a consequence of the underlying quantum field dynamics.
  • Quantum Information Theory: Quantum information theory provides a framework for understanding entanglement in terms of information processing and quantum computation. Entangled states can be used to perform tasks such as quantum teleportation and quantum cryptography.
  • Many-Worlds Interpretation: According to the Many-Worlds Interpretation of quantum mechanics, entanglement arises from the branching of the universe into multiple parallel realities. When two particles become entangled, their states are correlated across different branches of the wave function.
  • Bohmian Mechanics: Bohmian mechanics is a deterministic interpretation of quantum mechanics that posits the existence of hidden variables to explain the apparent randomness of quantum phenomena. In the context of entanglement, Bohmian mechanics provides a deterministic account of how the states of entangled particles are correlated.
  • Quantum Field Theory on Curved Spacetime: Some researchers have explored the role of curved spacetime in understanding entanglement. Quantum field theory on curved spacetime can lead to non-trivial entanglement patterns that may shed light on the nature of entanglement in curved spacetime regions.
Overall, the explanation for quantum entanglement remains a topic of active research and debate in the field of theoretical physics. Different interpretations offer varying perspectives on the nature of entanglement and its implications for our understanding of the quantum world.
