quantum-simulation has only one question and no description, but the question would fit with simulation which has a description and many questions. Should quantum-simulation be marked a synonym of simulation?
Yes, these tags should be synonymized.
The tags seem to cover the exact same thing, and one is definitely more widely used and self-explanatory than the other.
I think we should have two different tags, one for quantum simulation in the sense of using a quantum system to simulate another one, and the other for the problem of simulating quantum systems with classical devices.
For example, this and this questions are about simulation but not about quantum simulation, while this and this are about quantum simulation (though the last one is more specifically about hamiltonian simulation).
Perhaps we could have quantum-simulation and classical-simulation, and make
simulation as synonym for
The rationale about synonymizing
simulation this way is that I would expect people not knowing the difference to be more likely asking about
