Query: Introducing Quantum Entanglement to First-Year Students: Resolving the
  Trilemma   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. 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.
