For the following code
qc = QuantumCircuit(2) qc.cx(0,1) qc.measure_all() qc.draw()
Q1: What this vertical dotted line represent in the below circuit diagram?
Q2: 'meas' wire in the circuit is what kind of wire? is this classical wire or qubit wire?
Q3: How qc.measure_all() is different from qc.measure([0,1],[0,1])[couldn't find a simple answer on internet]
