Qiskit NoiseModel.from_backend gives wrong gate error

According to the Qiskit documentation, a gate error is simulated by a thermal relaxation channel followed by a depolarisation channel, where the parameter of the depolarisation channel is adjusted so ...

How can I get fidelity of a gate from randomized benchmarking?

I found (page 33) the method of finding fidelity from fit by "interleaved and reference decay" according to the sequence fidelity formula: $$F_{ref}=Ap_{ref}^{m}+B,$$ where $p_{ref}^{m}$ is ...

Calculate average fidelity of QobjEvo

I am using QuTip to simulate a quantum gate, and I want to calculate the average fidelity of the gate. I have the Hamiltonian, the interaction time, and Liouvillian modeling the decoherence. Is there ...

How to extract the entanglement fidelity from an arbitrary quantum operation?

I have an arbitrary process matrix that does an entangling operation (a controlled-pi/2 rotation) plus some additional phase rotations that are not of interest. I am curious to find a way to extract a ...
