@Martin, I have rephrased and changed my question.

I can't even ask the author as he is no more alive. :(

comment Change in Shannon entropy of a quantum circuit of Hadamard gate and a loop
@Goodies, after a quick review I failed to find a section in that paper which is discussing about the heat dissipation of a reversible circuit. The author didn't discuss about the inapplication of Landauer's principle for any implementation of reversible circuits. Am I missing anything?

comment Eigenvalue of the adiabatic Hamiltonian of Farhi's three qubit 2-SAT problem
Jeffrey Goldstone replied to my email. He suggested to use an $8 \times 8$ Hadamard matrix as $H_B$. For $H_P$ he suggested to use the projector $I - |ground-state-of-H-imply><ground-state-of-H-imply| - |ground-state-of-H-disagree><ground-state-of-H-disagree| - |ground-state-of-H-agree><ground-state-of-H-agree|$. I am going to fix accordingly.

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."
