"## Setup\n",
"In this section we configure the hardware configuration which specifies the connectivity of our system.\n",
"\n",
"The experiments of this tutorial are meant to be executed with a Qblox Cluster controlling a transmon system.\n",
"The experiments can also be executed using a dummy Qblox device that is created via an instance of the `Cluster` class, and is initialized with a dummy configuration.\n",
"When using a dummy device, the analysis will not work because the experiments will return `np.nan` values.\n",
"\n",
"### Configuration file\n",
"\n",
"This is a template hardware configuration file for a 2-qubit system with a flux-control line which can be used to tune the qubit frequency. We will only work with qubit 0.\n",
"\n",
"The hardware connectivity is as follows, by cluster slot:\n",
"\n",
"- **QCM** (Slot 2)\n",
" - $\\text{O}^{1}$: Flux line for `q0`.\n",
" - $\\text{O}^{2}$: Flux line for `q1`.\n",
"\n",
"- **QCM-RF** (Slot 6)\n",
" - $\\text{O}^{1}$: Drive line for `q0` using fixed 80 MHz IF.\n",
" - $\\text{O}^{2}$: Drive line for `q1` using fixed 80 MHz IF.\n",
"\n",
"- **QRM-RF** (Slot 8)\n",
" - $\\text{O}^{1}$ and $\\text{I}^{1}$: Shared readout line for `q0`/`q1` using a fixed LO set at 7.5 GHz.\n",
"\n",
"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."
