qbraid.runtime.QuantumDevice

class QuantumDevice(profile, scheme=None, **kwargs)

Abstract interface for quantum devices.

Create a QuantumDevice object.

Parameters:

• profile (TargetProfile) – The device runtime profile.

• scheme (Optional[ConversionScheme]) – The conversion graph and options passed to the transpiler at runtime.

__init__(profile, scheme=None, **kwargs)

Create a QuantumDevice object.

Parameters:

• profile (TargetProfile) – The device runtime profile.

• scheme (Optional[ConversionScheme]) – The conversion graph and options passed to the transpiler at runtime.

Methods

__init__(profile[, scheme])	Create a QuantumDevice object.
apply_runtime_profile(run_input)	Process quantum program before passing to device run method.
metadata()	Returns a dictionary containing selected metadata about the device.
queue_depth()	Return the number of jobs in the queue for the backend
run(run_input, *args, **kwargs)	Run a quantum job or a list of quantum jobs on this quantum device.
status()	Return device status.
submit(run_input, *args, **kwargs)	Vendor run method.
transform(run_input)	Override this method with any runtime transformations to apply to the run input, e.g. circuit optimizations, device-specific gate set conversions, etc.
transpile(run_input, run_input_spec)	Convert circuit to package compatible with target device and pass through any provider transpile methods to match topology of device and/or optimize as applicable.
update_scheme(**kwargs)	Update the conversion scheme with new values.
validate(program)	Verifies device status and circuit compatibility.

Attributes

id	Return the device ID.
num_qubits	The number of qubits supported by the device.
profile	Return the runtime profile.
scheme	Return the conversion scheme.
simulator	The device type, Simulator, Fake_device or QPU.
