• Abstract summary: The concept of quantum entanglement is typically not covered at all in introductory physics textbooks. We resolve this trilemma in precisely the same way that Einstein resolved the mysteries of time dilation and length contraction. Our principle account of quantum entanglement is even based on the same principle Einstein used.

• Abstract: While quantum mechanics (QM) is covered at length in introductory physics textbooks, the concept of quantum entanglement is typically not covered at all, despite its importance in the rapidly growing area of quantum information science and its extensive experimental confirmation. Thus, physics educators are left to their own devices as to how to introduce this important concept. Regardless of how a physics educator chooses to introduce quantum entanglement, they face a trilemma involving its mysterious Bell-inequality-violating correlations. They can compromise on the the completeness of their introduction and simply choose not to share that fact, totally ignoring the 2022 Nobel Prize in Physics. They can frustrate their more curious students by introducing the mystery and simply telling them that the QM formalism with its associated (equally mysterious) conservation law maps beautifully to the experiments, so there is nothing else that needs to be said. Or, they can compromise the rigor of their presentation and attempt to resolve the mystery by venturing into the metaphysical quagmire of competing QM interpretations. Herein, we resolve this trilemma in precisely the same way that Einstein resolved the mysteries of time dilation and length contraction that existed in the late nineteenth century. That is, we resort to "principle" explanation based on the mathematical consequences of "empirically discovered" facts. Indeed, our principle account of quantum entanglement is even based on the same principle Einstein used, i.e., the relativity principle or "no preferred reference frame." Thus, this principle resolution of the trilemma is as complete, satisfying, analytically rigorous, and accessible as the standard introduction of special relativity for first-year physics students.

  We argue that the gist of the Wigner's friend paradox can be reproduced without assuming quantum physics. We show that several recently proposed extended Wigner's friend scenarios can be reproduced by classical thought experiments. We argue that this difficulty is at the core of other puzzles in the foundations of physics and philosophy.

  Quantum measurement is a fundamental concept in the field of quantum mechanics. Despite its significance, four fundamental issues continue to pose significant challenges to the broader application of quantum measurement. We employ a new space-time approach to relativistic quantum mechanics to address these issues systematically.

Here, we unveil distinct exceptional entanglement phenomena, exemplified by an entanglement transition, occurring at the exceptional point of NH interacting quantum systems. Our results lay the foundation for studies of genuinely quantum-mechanical NH physics, signified by exceptional-point-enabled entanglement behaviors.

  I propose a slight addition to standard textbook quantum mechanics, in the form of two rules, which avoids the paradox. The first specifies when a given quantum dynamics can be interpreted as a measurement. The second requires that a joint context be used to determine whether several different dynamical evolutions can all be interpreted as measurement.
