Set the sampled errors to be applied before the original operation

set number of threads per group(GPU)

Special handling for setting backend options. This method should be extended by sub classes to update special option values.

Set random seed for the RNG engine

Set the sample_measure index size

Gets the status of the job by querying the Python's future Returns: JobStatus: The current JobStatus Raises:

Submit the job to the backend for execution. Raises: QobjValidationError: if the JSON serialization of the Qobj passed

Return a list errors for the subsystem decomposed error. .. note:: This uses a greedy algorithm to find the largest non-identity

Return T1, T2 and frequency values from a devices BackendProperties. Args: properties (BackendProperties): device backend propertie

Return the current error as a dictionary.

Return a dictionary format representation of the GateConfig. Returns: dict: The dictionary form of the GateConfig.

Return a dictionary format representation of the circuit. Returns: dict: The dictionary form of the CircuitHeader.

Return a dictionary format representation of the BackendStatus. Returns: dict: The dictionary form of the Gate.

Return a dictionary format representation of the BackendProperties. Returns: dict: The dictionary form of the BackendProperties.

Convert the QuantumError to a circuit Instruction.

Return a statevector from a pure density matrix. Args: atol (float): Absolute tolerance for checking operation validity.

check if this register is on the top of array (always true if array is allocated independently)

Return a new quantum error containin transpiled circuits. This returns a new QuantumError containing the circuits resulting from transpiling
