comment Confusion about a lemma on the time constraint of an adiabatic evolution (arXiv:quant-ph/0604077)
The author replied as follows: To be frank, both of the two interpretations are inaccurate. The proofs are exactly for the cases listed only, and do not work for any other situation. Besides, I think the complexity to make a statement for a case as general as your first interpretation is probably NP-hard.

comment Confusion about a lemma on the time constraint of an adiabatic evolution (arXiv:quant-ph/0604077)
Can I simply interpret the Theorem 1 as follows? "If the eigenstate of the initial Hamiltonian are superposition of all possible states we cannot perform the adiabatic evolution with a diagonal Hamiltonian as the problem Hamiltonian. " Can I simply interpret the Theorem 2 as follows? "Having diagonal Hamiltonians as both initial and problem Hamiltonians will not work."

The author echoed your answer. Thanks. I just asked them the following though.

@Ali, is it possible to trap a photon or biphoton in a potential well?

comment Adiabatic theorem in the regime of quantum optics
@PeterShor, Is that even possible? I think a prerequisite is to have single photon or biphoton system with ground and higher energy level. I am not sure how one can make such state. So I asked a separate question here (physics.stackexchange.com/questions/72863/…)
