I am confused of all that different Quantum computers.

please correct me if I say something wrong.

There are two main different types of quantum computing:

  1. Quantum Gates based computing
  2. quantum annealing

For quantum gate based computing, I know that there are different kind of architectures -- that's clear for me.

But why I am so confused is, there is the Quantum Annealing, which is used by D-Wave Systems and that Q. annealer is using the adiabatic theorem , right ?

So then we can say that Adiabatic Quantum Annealer = Quantum Annealer ?

The next confusing term is Adiabatic Quantum Computer , is that Adiabatic Quantum Annealer?

And the last is what is Quantum Simulator ? Where is that used ? which type of quantum computing are that simulated? And is there a difference between them and quantum annealing ?

Too many questions :/
