How can I implement a circuit that simulates white noise on $n$ qubits?
I want to test an error model of the convex form
$$t \times \text{ideal_state} + (1-t)\times \text{noisy_circuit}.$$
In terms of density matrices, this would look like
$$t\rho_{\text{idealState}}+(1-t)...

How to add command `noise_model = get_noise ( 0.05,0.05 )` to my simulator in qiskit
I'm using qiskit online, and want to run my simulator with the following command:
noise_model = get_noise ( 0.05,0.05 )
However, where previously I could insert lines of code to affect my circuit, I ...
