Very general question so I'm not looking for an exact answer.
I just want a basic description of certain ways it can be done and then if possible the names of those ways, so that I can look them up further.
But I want to know, if I was to run some code in a quantum computing language, how would a classical computer interface with the quantum one to instruct it?
Contact the machinery that directly builds a full circuit and then run it? Does it go line by line and apply the gate at each stage? Can it just directly communicate with the qubits?
Note: I am looking for answers for both gate based and continous computing
