These may be set using the appropriate kwargs during initialization. They can also be set of updated using the :meth:`set_options` method. Run-time options may also be specified as kwargs using the :meth:`run` method. These will not be stored in the backend and will only apply to that execution. They will also override any previously set options. For example, to configure a a single-precision simulator .. code-block:: python backend = UnitarySimulator(precision='single') **Backend Options** The following configurable backend options are supported * ``device`` (str): Set the simulation device (Default: ``"CPU"``). Use :meth:`available_devices` to return a list of devices supported on the current system. * ``method`` (str): [DEPRECATED] Set the simulation method supported methods are ``"unitary"`` for CPU simulation, and ``"unitary_gpu"`` for GPU simulation. This option has been deprecated, use the ``device`` option to set "CPU" or "GPU" simulation instead. * ``precision`` (str): Set the floating point precision for certain simulation methods to either ``"single"`` or ``"double"`` precision (default: ``"double"``). * ``executor`` (futures.Executor): Set a custom executor for asynchronous running of simulation jobs (Default: None). * ``max_shot_size`` (int or None): If the number of shots of a noisy circuit exceeds this value simulation will be split into multi circuits for execution and the results accumulated. If ``None`` circuits will not be split based on shots. When splitting circuits use the ``max_job_size`` option to control how these split circuits should be submitted to the executor (Default: None). * ``max_shot_size`` (int or None): If the number of shots with a noise model exceeds this value, simulation will split the experiments into sub experiments. If ``None`` simulator does nothing (Default: None). * ``"initial_unitary"`` (matrix_like): Sets a custom initial unitary matrix for the simulation instead of identity (Default: None). * ``"validation_threshold"`` (double): Sets the threshold for checking if initial unitary and target unitary are unitary matrices. (Default: 1e-8). * ``"zero_threshold"`` (double): Sets the threshold for truncating small values to zero in the result data (Default: 1e-10). * ``"max_parallel_threads"`` (int): Sets the maximum number of CPU cores used by OpenMP for parallelization. If set to 0 the maximum will be set to the number of CPU cores (Default: 0). * ``"max_parallel_experiments"`` (int): Sets the maximum number of experiments that may be executed in parallel up to the max_parallel_threads value. If set to 1 parallel circuit execution will be disabled. If set to 0 the maximum will be automatically set to max_parallel_threads (Default: 1). * ``"max_memory_mb"`` (int): Sets the maximum size of memory to store a state vector. If a state vector needs more, an error is thrown. In general, a state vector of n-qubits uses 2^n complex values (16 Bytes). If set to 0, the maximum will be automatically set to the system memory size (Default: 0). * ``"statevector_parallel_threshold"`` (int): Sets the threshold that 2 * "n_qubits" must be greater than to enable OpenMP parallelization for matrix multiplication during execution of an experiment. If parallel circuit or shot execution is enabled this will only use unallocated CPU cores up to max_parallel_threads. Note that setting this too low can reduce performance (Default: 14). These backend options apply in circuit optimization passes: * ``fusion_enable`` (bool): Enable fusion optimization in circuit optimization passes [Default: True] * ``fusion_verbose`` (bool): Output gates generated in fusion optimization into metadata [Default: False] * ``fusion_max_qubit`` (int): Maximum number of qubits for a operation generated in a fusion optimization [Default: 5] * ``fusion_threshold`` (int): Threshold that number of qubits must be greater than or equal to enable fusion optimization [Default: 7] unitary_simulatorrz$https://github.com/Qiskit/qiskit-aerTFg.AzA C++ unitary circuit simulatorN)9u1u2u3uprrxryrzidxyzhssdgsxsxdgttdgswapcxcyczcsxcucpcu1cu2cu3rxxryyrzzrzxccxcczcswapmcxmcymczmcsxmcumcpmcphasemcu1mcu2mcu3mcrxmcrymcrzmcrmcswapunitarydiagonal multiplexerdelaypauli) save_unitary save_state set_unitaryreset) backend_namebackend_versionn_qubitsurl simulatorlocal conditional open_pulsememory max_shots description coupling_map basis_gatescustom_instructionsgates)CPUGPUThrustc Ftdtt|_tjt |jt_|tjtj }nd|_ t ||||dS)NaThe `UnitarySimulator` backend will be deprecated in the future.
