in `FluxTunableTransmon` and `Transmon`:
1. why is `mixer` optional? We'd always want to upconvert the signals, no? Is it for a scenario where you don't want to do mixer calibration at all? Is it e…

The current `Transmon` class (`qua_qsim.architectures.transmon.Transmon`) does not include a readout resonator. However, in realistic systems the transmon is nearly always coupled to a readout resonat…

First of all, thank you very much for your tutorials in pyEPR, they saved me!
I'm a master student of Roma3, working at INFN for a design of two transmon qubits.
The code I'm using is simi…

The noise rate due to quasiparticle tunneling is zero. This is an unexpected behavior.
MWE:
```python
import SQcircuit as sq
C = sq.Capacitor(3, 'GHz')
JJ = sq.Junction(2., 'GHz', cap=C)
ele…

### What happened?
There is no subspace information in a control problem.
Consider a three level transmon
```Julia
η = -0.2
a = annihilate(3)
sys = QuantumSystem(η / 2 * a'*a'*a*a, [(a + a')…

In the past we had several discussion about the possibility of sweeping offset or flux amplitude in the [flux dependence ](https://qibo.science/qibocal/stable/protocols/flux/single.html) experiment. I…

### Describe the bug
When I set deepcopy = True and specify subsys_update_info when initializing the parameter sweep, the sweep can't recognize the subsystem objects in the subsys_update_info. The Pa…

Hi,
I try to simulate the single transmon qubit in the SQcircuit, but the output frequency and anharmonicity from the SQcircuit don't match the theoretical results. Here is my code.
import SQcir…
