qat.purr.integrations.qiskit module

class QatBackend(hardware=None, comp_config=None, **fields)

Bases: BasicSimulator

Basic qiskit backend built to run QASM on our own target machines.

TODO: Expand this to become a proper back-end, as I don’t believe we need to inherit

off the QASM simulator as it stands.

Args:

provider: An optional backwards reference to the

Provider object that the backend is from.

target: An optional target to configure the simulator. fields: kwargs for the values to use to override the default

options.

Raises:

AttributeError: If a field is specified that’s outside the backend’s

options.

run(qobj, **backend_options)

Run on the backend.

Args:

run_input: payload of the experiment backend_options: backend options

Returns:

BasicProviderJob: derived from BaseJob

Additional Information:

backend_options: Is a dict of options for the backend. It may contain

• “initial_statevector”: vector_like

The “initial_statevector” option specifies a custom initial initial statevector for the simulator to be used instead of the all zero state. This size of this vector must be correct for the number of qubits in run_input parameter.

Example:

backend_options = {
    "initial_statevector": np.array([1, 0, 0, 1j]) / math.sqrt(2),
}

run_qasm(qasm_str)

Runs the passed-in QASM string against the QASM state simulator.

run_qasm_circuit(circuit)

run_qasm_from_file(qasm_file)

Runs the passed-in QASM file against the QASM state simulator.
