Typically superconducting qubits can be controlled independently, eg. due to having separate control wires. So you'd have independent pulses in each control wire applying a gate to the respective qubits. The gates can be done at the same time. Due to crosstalk, it can matter if operations are done at the same time or one after the other. Doing them at the ...

If you initialize three qubits to $|0\rangle$, apply a Hadamard gate to each, then measure each in the computational basis, the result will be an independent coin flip for each bit: that is, any of 000, 001, 010, ..., 111, each with probability 1/8. If you measure all three bits of the GHZ state in the computational basis, you'll get either 000 or 111, each ...
