How can visualise the old error map of Ibm backend if one save the calibration data of the backend at that time?
I have the calibration data of an Ibm backend and now I want to plot the error map of the device at that specific time.
How can I do this?

Exploiting virtual-$Z_{\theta}$ corrections in QEC
The work done by IBM Researchers to perform virtual-$Z_{\theta}$ gates allowed them to:
achieving zero-time relative phase shifts;
correcting $Z_{\phi}$ errors occurring when applying some gates -- e....

Is it possible to get access to the old noise model from a few months ago for Ibmq backends?
I performed an experiment on a real Ibmq backend, and the results were satisfactory. I now require the simulation of that experiment. The simulation is not sufficiently consistent with the old ...

How does it work QasmSimulator with the option "density matrix"?
I am making some simulations on IBM Quantum Lab and as backend I tried to use QasmSimulator(method = "density_matrix") in order to simulate noise. I wanted to know how this method works in ...

Is Noise model for quantum prototypes accurate in Qiskit
We know that in Qiskit noise models modeling specific quantum machine prototypes exist and can be inserted into the code. However, are these models fixed in nature or they continuously improve ...
