# ## Setup
# In this section we configure the hardware configuration which specifies the connectivity of our system.

# %% [markdown]
# ### Configuration file
#
# This is a template hardware configuration file for a 1-qubit system with a flux-control line which can be used to tune the qubit frequency.
#
# The hardware setup is as follows, by cluster slot:
# 6. **QCM-RF**
#     - Drive line for `qubit` using fixed 80 MHz IF.
# 2. **QCM**
#     - Flux line for `qubit`.
# 8. **QRM-RF**
#     - Readout line for `qubit` using a fixed LO set at 7.5 GHz.
# `sequence_to_file` is a boolean flag which dumps waveforms and program dict to JSON file if `True`.
# `"ref": "internal"` specifies the use of the shared clock reference of the cluster
#

# Note that in the hardware configuration below the mixers are uncorrected, but for high fidelity experiments this should also be done for all the modules.

# ### Configure external flux control
# In the case of flux-tunable transmon qubits, we need to have some way of controlling the external flux.
#
# This can be done by setting an output bias on a module of the cluster which is then connected to the flux line.
#
# ```python
#     # e.g. nullify external flux by setting current to 0 A
#     cluster.module2.out0_current(0.0)
# ```
#
# If your system is not using flux-tunable transmons, then you can skip to the next section.

# %% [markdown]
# ### Activate NCO delay compensation
# Compensate for the digital propagation delay for each qubit (i.e each sequencer)
#
#
# To avoid mismatches between modulation and demodulation, the delay between any readout frequency or phase changes and the next acquisition should be equal or greater than the total propagation delay (146ns + user defined value).

# ## Characterization experiments
# The sweep setpoints for all experiments (e.g. `frequency_setpoints` in the spectroscopy experiments) are only examples. The sweep setpoints should be changed to match your own system.
#
# We show two sets of experiments: The first contains generic characterization experiments for transmon qubits. The second contains 2D experiments for finding the flux sweetspot, applicable for flux-tunable qubits.
#
#
# Here we consider five standard characterization experiments for single qubit tuneup. The experiments are:
# 1. Resonator spectroscopy
#     - Used to find the frequency response of the readout resonator when the qubit is in $|0\rangle$.
