qrmi.primitives.ibm.backend module#

IBMBackend implementation with IBM QRMI

class qrmi.primitives.ibm.backend.QRMIBackend(qrmi: QuantumResource, **fields)[source]#

Bases: BackendV2

Backend class interfacing with an IBM Quantum backend.

check_faulty(circuit: QuantumCircuit) → None[source]#

Check if the input circuit uses faulty qubits or edges.

Parameters:: circuit – Circuit to check.
Raises:: ValueError – If an instruction operating on a faulty qubit or edge is found.

configuration() → QasmBackendConfiguration[source]#

Return the backend configuration.

Backend configuration contains fixed information about the backend, such as its name, number of qubits, basis gates, coupling map, quantum volume, etc.

The schema for backend configuration can be found in Qiskit/ibm-quantum-schemas/backend_configuration.

More details about backend configuration properties can be found here QasmBackendConfiguration.

IBM backends may also include the following properties:

supported_features: a list of strings of supported features like “qasm3”
for dynamic circuits support.
parallel_compilation: a boolean of whether or not the backend can process multiple
jobs at once. Parts of the classical computation will be parallelized.

Returns:: The configuration for the backend.

property dtm: float#

Return the system time resolution of output signals

Returns:: The output signal timestep in seconds.
Return type:: dtm

get_translation_stage_plugin() → str[source]#: Return the default translation stage plugin name for IBM backends.

property max_circuits: None#: This property used to return the max_experiments value from the backend configuration but this value is no longer an accurate representation of backend circuit limits. New fields will be added to indicate new limits.

property meas_map: List[List[int]]#

Return the grouping of measurements which are multiplexed

This is required to be implemented if the backend supports Pulse scheduling.

Returns:: The grouping of measurements which are multiplexed
Return type:: meas_map

properties(refresh: bool = False) → BackendProperties | None[source]#

Return the backend properties, subject to optional filtering.

This data describes qubits properties (such as T1 and T2), gates properties (such as gate length and error), and other general properties of the backend.

The schema for backend properties can be found in Qiskit/ibm-quantum-schemas/backend_properties.

Parameters:

refresh – If True, re-query the server for the backend properties. Otherwise, return a cached version.

Returns:

The backend properties or None if the backend properties are not currently available.

Raises:

TypeError – If an input argument is not of the correct type.
NotImplementedError – If datetime is specified when cloud runtime is used.

refresh() → None[source]#: Retrieve the newest backend configuration and refresh the current backend target.

run(*args, **kwargs) → None[source]#

Raises:: IBMBackendError – The run() method is no longer supported.

status() → BackendStatus[source]#

Return the backend status.

Returns:: The status of the backend.

property target: Target#

A :class:qiskit.transpiler.Target object for the backend.

Returns:: Target

qrmi.primitives.ibm.backend.get_backend(qrmi: QuantumResource, use_fractional_gates: bool | None = False) → Backend[source]#

Returns Qiskit transpiler target

Parameters:

qrmi – IBM QRMI object
use_fractional_gates – Whether to use native “fractional gates” on the device if available.

Returns:

Qiskit Transpiler target

Return type:

qiskit.transpiler.target.Target

qrmi.primitives.ibm.estimator module#

EstimatorV2 Primitive implementation with IBM QRMI

class qrmi.primitives.ibm.estimator.EstimatorV2(qrmi: QuantumResource, *, options: dict | None = None)[source]#

Bases: QRMIBaseEstimatorV2

EstimatorV2 for QRMI

qrmi.primitives.ibm.sampler module#

SamplerV2 Primitive implementation with IBM QRMI

class qrmi.primitives.ibm.sampler.SamplerV2(qrmi: QuantumResource, *, options: dict | None = None)[source]#

Bases: QRMIBaseSamplerV2

SamplerV2 for QRMI

qrmi.primitives.ibm.target module#

Qiskit Target creation

qrmi.primitives.ibm.target.get_target(qrmi: QuantumResource) → Target[source]#

Returns Qiskit transpiler target

Parameters:: qrmi – IBM QRMI object
Returns:: Qiskit Transpiler target
Return type:: qiskit.transpiler.target.Target
