A model for noise in quantum systems such as a decohering qubit that has particularly nice symmetry properties. The depolarizing channel is a “worst-case scenario” channel. It assumes that we just completely lose the input qubit with some probability, i.e., it replaces the lost qubit with the maximally mixed state.

What is an instruction when we `add_all_qubit_quantum_error`?
This depends on your circuit. If you have only 1-qubit gates, you can construct a noise model from single-qubit errors. But if you want to do something interesting, you need to entangle your qubits wi …

How do I apply depolarization error on 2 qubits using Qiskit?
If you like to add a 2-qubit error to CNOT gates, you have to create a depolarizing error with err = depolarizing_error(param, num_qubits=2) which you may add to your noise model by noise_model.add_al …
