Does qiskit make any rounding errors or anything similar, or is it a perfect (but slow) simulation of a quantum computer?
I ran the following circuit to calculate the real part of the Bargmann Invariant of a system of quantum states. The invariant is defined as

Measurement of readout errors for error mitigation algorithms
I am using an error mitigation algorithm that uses the readout errors p(0|1) and p(1|0) to correct the errors due to noise in my original circuit. I am trying to measure the readout errors in the same ...

Qiskit, possible to manipulate mid-circuit measurement outcomes?
I'm currently coding up an error correction gadget using qiskit.
The one I'm doing now is 7-qubit Steane code with Steane's error correction gadget, in which the ancilla qubits are measured and then ...

How to do error mitigation on the ibmq_16_melbourne?
I'm trying to make a calibration matrix using CompleteMeasFitter as in here on IBMQ Melbourne, but I need to use all 15 qubits, which mean it has to run 32768 calibration circuit, far exceeding the 75 ...
