Wrong: The Aharonov–Bohm effect says something profound about the "reality" of potentials in quantum mechanicsRight: Non-zero forces on source charges, obscurred by the semi-classical limit, show that potentials are just as real (or ficticious) as they are classically.
Implication: "The core of the Aharonov-Bohm effect is the same as the core of quantum entanglement: the quantum wave function describes all systems together."
More: Lev Vaidman, arXiv:1110.6169.
Implication: The Aharonov–Bohm effect, like entanglement-enabled surpassing of the shot-noise limit, is a special case of a quantum-enhanced measurement.
More: C. Jess Riedel, arXiv:1205.3195. Wrong: Observables are "represented" (?) by Hermitian operators.
Right: Measurements necessarily amplify, and therefore (!) are associated with an orthogonal basis. This is the Schmidt basis of the entangled joint state of the measuring apparatus and the measured system.
More: Wojciech H. Zurek, Phys. Rev. A 76, 052110 (2007), [arXiv:quant-ph/0703160]. Also: [arXiv:1212.3245].
Implication: Observables can be associated with normal, not just Hermitian, operators.
