I'm currently involved in a PhD in Mathematics. My research area is that of Functional Analysis. Specifically I'm working on classification of C*-algebras by defining a bivariant version of the Cuntz semigroup, an invariant used to compare positive elements in a C*-algebra and hence infer information about its internal structure.

During my MSc I focused on Algebraic Quantum Field Theory and I have worked on DFR models for Quantum Space-time (arXiv:1211.7050 [gr-qc]).

they look like they are stuck to the cup.

comment Is the interference quantum mechanical superposition the same as entanglement?
For entangled states you can choose a vector state which factorises in the tensor product, so with this choice there is no superposition. Of course you can take an arbitrary base for the tensor product Hilbert space and decompose the entangled state in a superposition of other states, so as you can see from this there is no direct link between entanglement and superposition.

comment Is the interference quantum mechanical superposition the same as entanglement?
I'd say this is clearly not the context of classical physics, so classical interference of waves can be ruled out.

comment What was Feynman's famous formula?
rewrite any equation in such a way that the RHS is always 0. Assume that $a$ is the "sum" of all these equations, then $a=0$.

comment What sort of operations can be applied on a Hilbert spaces?
the example of flipping you gave is implemented by an antiunitary operator, so my feeling is that somehow this is related to the question whether antilinear operator should be considered or not. Unfortunately I'm not an expert of quantum computing/information so I don't really know the answer to this last question.

comment Field strength is always closed?
$dF=0\Rightarrow F=dA$ is a consequence of the triviality of the first de Rahm cohomology group of $\mathbb R^4$, so unless clear from the context, it is in principle necessary to specify the ambient manifold.
