            This looks like it's just a network issue. The error is a timeout trying to read from files.pythonhosted.org when pip was downloading the qiskit-terra package from PyPI. There isn't really anything you can do except to try again in such cases. If you're on a slow and/or unreliable internet connection it might take several tries take a few tries for the download of all the qiskit packages (and their dependencies) to succeed.

            My qiskit code's output differ from the Lecturer: Ryan O’Donnell

            I am testing the table shown in attached image by using qiskit in python3.8.5 and qiskit version {'qiskit-terra': '0.14.2', 'qiskit-aer': '0.5.2', 'qiskit-ignis': '0.3.3', 'qiskit-ibmq-provider': '0.7.2', 'qiskit-aqua': '0.7.3', 'qiskit': '0.19.6'}

            my code is :

            ANSWER

            Answered 2020-Aug-10 at 14:42

            Ahh, I think I see the issue. In the table from lecturer Ryan O'Donnell, the state is read from the first qubit to the last qubit. For example, the state |110> means that the qubit labelled q_0 is in state |1>, q_1 is in state |1> and q_2 is in state |0>. In Qiskit, the label convention is reversed. So, in Qiskit, |110> would actually be read as |011>, since the state is read from the last to the first qubit. So, your code and output is correct, since in Ryan O'Donnell's table, your state |011> is |110>. If this doesn't make sense, let me know.

            As to your new code, the reason why you are getting different results than expected is that as you run your for loop, instead of creating new circuits, you are consistently adding to an existing circuit. For example, when applying the first function, bit_000, you apply to ccx gate, barrier, and measure. Then calling bit_001, you add an x gate to q_0 and do the same thing. So far everything is good. Then you add an x gate to q_1 and do the same procedure, but you get the resulting state vector '111'. That is because in qiskit, it thinks there is an x gate on the first and second qubit, so when you apply the ccx gate, you get the result you get. So really, by applying all of those circuit operations, you've made one big circuit instead of 8 isolated circuits. I would initialize all the qubits to the state |0> after each time you measure, which will give you a clean slate to work off for the next circuit. With that edit, you should get the results that are written in Ryan O'Donnell's lecture. Hope this helps!
