comment How can a photon have no mass and still travel at the speed of light?
There can also exist massive point particles. The introduction of length contraction is really irrelevant here.

Compaction due to length contraction is not a valid concept for a point particle like a photon, and in any case, it is not related to increase in relativistic mass.

comment (thought) experiment re: Bell's Theorem and Schrodinger's cat
That's all right. Paradoxes are a nice way to really think about a system and understand what goes on properly. :)

comment Is boson sampling a problem in 'continuous variable' quantum information?
Thanks for the answer! I'll hold from accepting it for now because I would like to see some more discussion on the precise meaning of continuous variables in CV quantum information.

comment Quantum Mechanics mistake in partial trace
Of the three terms you have written in the last line, it's the second term that leads to $\mathrm{Tr}\rho \neq 1$. Can you check that term again?

comment Causality for the Dirac Field
Thank you! I had a similar question for a long time. Which sections from the text would you recommend me to read if I want to understand the measurable quantities properly? For example, nowhere in Peskin and Schroeder's book do they define properly what the field $\phi$ exactly is, and what the basis actually means. It becomes implicit only later, when we see that $a_{\bar{p}}^{\dagger}|0\rangle $ is a one-particle momentum eigenstate with 3-momentum $\bar{p}$.

revised Why does a difference in approach to projectile motion yields different results?
Fixed grammar- correction in number of the noun.

revised How are the definitions of a coherent state equivalent?
Updated link to go to the relevant formula directly.
