ConfigLoader Example¶

This notebook reads shared example config files from docs/examples/system/config and system-specific parameter files from docs/examples/system/params/<system_id>, then loads them with ConfigLoader.

In [ ]:

from pathlib import Path

import yaml

from qubex.system import ConfigLoader

from pathlib import Path import yaml from qubex.system import ConfigLoader

Resolve example paths¶

Choose one of 64Q-HF-Q1, 144Q-LF-Q1, or 144Q-LF-Q3, and the notebook resolves the shared config directory together with the matching parameter directory.

This supports running the notebook from the repository root, docs/examples/system, or one of its child directories.

In [ ]:

system_id = "144Q-LF-Q3"
supported_system_ids = {"64Q-HF-Q1", "144Q-LF-Q1", "144Q-LF-Q3"}
if system_id not in supported_system_ids:
    raise ValueError(f"Unsupported system_id: {system_id}")

candidate_root_dirs = [
    Path.cwd(),
    Path.cwd() / "docs/examples/system",
    Path.cwd().parent,
    Path.cwd().parent.parent,
]

example_root = next(
    (
        path
        for path in candidate_root_dirs
        if (path / "config").is_dir() and (path / "params").is_dir()
    ),
    None,
)
if example_root is None:
    raise FileNotFoundError(
        "Could not find `docs/examples/system/{config,params}` from the current working directory."
    )

config_dir = example_root / "config"
params_dir = example_root / "params" / system_id

print(f"example_root: {example_root.resolve()}")
print(f"system_id   : {system_id}")
print(f"config_dir  : {config_dir.resolve()}")
print(f"params_dir  : {params_dir.resolve()}")

system_id = "144Q-LF-Q3" supported_system_ids = {"64Q-HF-Q1", "144Q-LF-Q1", "144Q-LF-Q3"} if system_id not in supported_system_ids: raise ValueError(f"Unsupported system_id: {system_id}") candidate_root_dirs = [ Path.cwd(), Path.cwd() / "docs/examples/system", Path.cwd().parent, Path.cwd().parent.parent, ] example_root = next( ( path for path in candidate_root_dirs if (path / "config").is_dir() and (path / "params").is_dir() ), None, ) if example_root is None: raise FileNotFoundError( "Could not find `docs/examples/system/{config,params}` from the current working directory." ) config_dir = example_root / "config" params_dir = example_root / "params" / system_id print(f"example_root: {example_root.resolve()}") print(f"system_id : {system_id}") print(f"config_dir : {config_dir.resolve()}") print(f"params_dir : {params_dir.resolve()}")

Read config files directly¶

In [ ]:

config_payloads = {}
for path in sorted(config_dir.glob("*.yaml")):
    with path.open() as f:
        config_payloads[path.name] = yaml.safe_load(f)

system_entry = config_payloads["system.yaml"][system_id]

print("loaded files:", ", ".join(config_payloads))
print("system backend:", system_entry["backend"])
print("chip id:", system_entry["chip_id"])

config_payloads = {} for path in sorted(config_dir.glob("*.yaml")): with path.open() as f: config_payloads[path.name] = yaml.safe_load(f) system_entry = config_payloads["system.yaml"][system_id] print("loaded files:", ", ".join(config_payloads)) print("system backend:", system_entry["backend"]) print("chip id:", system_entry["chip_id"])

Load the same files with ConfigLoader¶

In [ ]:

loader = ConfigLoader(
    system_id=system_id,
    config_dir=config_dir,
    params_dir=params_dir,
    autoload=False,
)
loader.load()
system = loader.get_experiment_system()

print("system_id    :", loader.system_id)
print("chip_id      :", loader.chip_id)
print("backend_kind :", loader.backend_kind)
print("wiring_file  :", loader.wiring_file)
print("qubits       :", len(system.qubits))
print("resonators   :", len(system.resonators))
print("boxes        :", len(system.boxes))

loader = ConfigLoader( system_id=system_id, config_dir=config_dir, params_dir=params_dir, autoload=False, ) loader.load() system = loader.get_experiment_system() print("system_id :", loader.system_id) print("chip_id :", loader.chip_id) print("backend_kind :", loader.backend_kind) print("wiring_file :", loader.wiring_file) print("qubits :", len(system.qubits)) print("resonators :", len(system.resonators)) print("boxes :", len(system.boxes))

Access loaded parameters¶

In [ ]:

first_qubit = system.qubits[0].label
print("first qubit label      :", first_qubit)
print(
    "control amplitude      :", system.control_params.get_control_amplitude(first_qubit)
)
print(
    "readout amplitude      :", system.control_params.get_readout_amplitude(first_qubit)
)
print("MUX0 capture delay     :", system.control_params.get_capture_delay(0))

first_qubit = system.qubits[0].label print("first qubit label :", first_qubit) print( "control amplitude :", system.control_params.get_control_amplitude(first_qubit) ) print( "readout amplitude :", system.control_params.get_readout_amplitude(first_qubit) ) print("MUX0 capture delay :", system.control_params.get_capture_delay(0))
