Is it possible to get the value of a measurement stored in the classical register in qiskit? Say that I have

q = QuantumRegister(9)
c = ClassicalRegister(9)
circuit = QuantumCircuit(q, c)

And I measure each qubit as

circuit.measure(q[i],c[i])

Then what I see when I print out any value in c[i] is Clbit(ClassicalRegister(9, 'c3'), 0). I'm wondering how I can see what the actual value of the individual classical bit is? Can I do it without having to first execute the job (i.e. so that I can utilize the value in a mid-circuit measurement scenario)?

  • $\begingroup$ @MartinVesely No, I mean can we get the values stored in the classical register without having to execute the job. Like, if I wanted to perform operations dependent on the classical register before executing $\endgroup$ May 10 at 5:42

    $\begingroup$ Qiskit allows you to perform mid-circuit measurement and to act accordingly to what was measured: quantumcomputing.stackexchange.com/questions/28010/… However, you do need to execute a job to get the values. Think about it: the classical register contains the result of a measurement performed on a quantum state. In order for this state to have been created, it is of course required that a job has been run. $\endgroup$ May 10 at 8:11
