High School How to evaluate whether a photon's polarization is in superposition?

Click For Summary
The discussion centers on the evaluation of a photon's polarization state to determine if it is in superposition. It highlights that a photon is always in a superposition in some basis, similar to how electric field vectors exist as superpositions of their components. Participants seek an accepted experimental methodology for assessing this superposition in polarization. The analogy between quantum superposition and electric field superposition is emphasized to clarify the concept. Understanding these principles is crucial for advancing experimental techniques in quantum mechanics.

Is there an accepted experimental methodology for determining whether a photon's polarization is in superposition or not?

I think of quantum superposition the same way I think of electric field superposition. An electric field vector exists in space and is always a superposition of its components in some basis. The same thought is applicable for quantum superposition.

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
